GLib-CRITICAL **: Source ID was not found when attempting to remove it - warning when leaving Network menu of g-c-c

Status changed to 'Confirmed' because the bug affects multiple users.

I was able to reproduce the bug following the steps above.

Now, for us to mark it triaged, we need an upstream bug to link to (in https://bugzilla.gnome.org/). Marked Low.

marking triaged.Thank you, blkperl.

Messages of the form "GLib-CRITICAL **: Source ID 6 was not found when attempting to remove it" also occur when running GParted.

For example on Ubuntu GNOME 14.04 beta1:

$ sudo apt-get install gparted
$ sudo gparted
======================
libparted : 2.3
======================

(gpartedbin:2677): GLib-CRITICAL ** Source ID 7 was not found when attempting to remove it

(gpartedbin:2677): GLib-CRITICAL ** Source ID 6 was not found when attempting to remove it

(gpartedbin:2677): GLib-CRITICAL ** Source ID 26 was not found when attempting to remove it
...

I have only seen this occur with Ubuntu 14.04. My suspicion is that there might be a regression in GLib, or possibly a mismatch with GTK and GLib.

After installing Ubuntu 14.04, I also get a ton of these messages when running banshee from a [gnome-]terminal, e.g.:
(Banshee:10804): GLib-CRITICAL **: Source ID 32103 was not found when attempting to remove it
(Banshee:10804): GLib-CRITICAL **: Source ID 32168 was not found when attempting to remove it

(They weren't present in 13.10.)

Also affecting console-kit-daemon:

In my case it started happening immediately after the upgrade from 13.10 to 14.04.

Exactly the same as Ariel's post above, lots of errors appearing on syslog:

Quote from an upstream (bugzilla.gnome.org) comment:

https://bugzilla.gnome.org/show_bug.cgi?id=721369

    GLib recently started throwing a warning when g_source_remove()
    is passed garbage (as per warning). Your applications have probably been broken
    for a while, and there's no telling what could actually have happened in the
    past when g_source_remove() would happily close any random source because the
    programmer got the wrong argument to g_source_remove().

So if true, it looks like this should be reasssigned either to Glib, or to all the affected applications.

The problem isn't just the error (log pollution). When the error occurs, I see ssh sessions actually hang when console-kit-daemon prints the error. This is a regression in 14.04 vs 13.10.

Any update to solve this message ? I have hell lot of messages being displayed :(

The upstream bug report for GParted can be found at the following link:

Bug number 729800 - Prevent GSource double-destroy warning messages
https://bugzilla.gnome.org/show_bug.cgi?id=729800

https://groups.google.com/forum/#!topic/vim_dev/Pmxb8swH1yE

Found this but dont know if this fixes it, I am getting the same error.

Can anyone confirm if this will work?

Got the same error when opening files with Sublime text 2 from the console

(sublime_text:15984): GLib-CRITICAL **: Source ID 1231 was not found when attempting to remove it

Same error with gparted. Multiple instances when launching and then again (multiple instances) while running a filesystem check.

example:

(gpartedbin:3683): GLib-CRITICAL **: Source ID 59 was not found when attempting to remove it

I just started noticing this due to logging 2 systems' syslog.

This is happening quite frequently source is console-kit-daemon according the the syslogs being recorded.

Sorry I have to correct my comment #10 above.

I found the direct reason for my session hangs and they are unrelated to this Glib-CRITICAL messages. Just conincidental.

The Glib-CRITICAL errors are annoying and indicate some incorrect calls from various apps to Glib, but not a serious issue as far as I'm concerned.

Same here but with nemo, xfce4-weather-plugin and gthumb (till now) seens version 14.04.1 LTS :

It's server without gdm so I just uninstalled consolekit, but still not sure why I get this error in first place

Hi,

This seems also affect Anjuta, in ubuntu 15.10 (so with glib 2.416.1) more badly as this faulty let think sourceview that the file saved was just deleted.

If you open a file with anjuta dev studio, make a change, and save, you get a warning message: "The file xxx has been deleted on the disk. Do you ant to close it ?" [Deleted] [Cancel]
this is due to g_file_monitor_file that faulty report a G_FILE_MONITOR_EVENT_DELETED

at this very exact moment, when enable debug for glib with G_MESSAGE_DEBUG=all (otherwise it is silent), glib raise a

I also get this "bug" about 10 times a day on a mythbuntu box that I barely even use! It could be coming from mythtv-frontend, lightdm, or a programme launched by lightdm.

I opened a bug #1528001 for f-spot package... may be I shoudn't have...

Why is this not getting fixed. It is clearly more than a nuance at this point.
The priority needs to be raised. What would that take to happen?

Bump, this also happens when running the new Eclipse installer from the terminal (Oomph). Is this related to SWT? Should we report the bug to SWT?

From reading this launchpad entry, I infer that it is a bug in each application that generates this. So perhaps my message should be reported against console-kit-daemon. Anyone know?

I have the same error within a test program using GtkTreeView + GtkTreeStore component from GTK+ 2. Thus, it seems to be a bug in GTK+.

@Dmitry:
Are you sure that you always have a valid id when calling g_source_remove(id), and that you call that function for each id only once?

@Manfred you may have fix this problem in ConsoleKit2 on Oct 5, 2014. Is this related?

I am on Mint 18.1. This problem affects me too. Is anyone working on it, please?

old and still not fixed:
(SWT:7981): GLib-CRITICAL **: Source ID 383 was not found when attempting to remove it

Ubuntu 16.10 kernel 4.11.8-041108-generic

@Karl Schindler:
What you see is probably a bug in Eclipse, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=479646
Something that eclipse has to work on.

thx Manfred

I see the same in my Ubuntu 16.04.3

(gnome-shell:3000): GLib-CRITICAL **: Source ID 3572546 was not found when attempting to remove it

Kernel 4.10.0-33-generic

apt-cache policy gnome-shell
gnome-shell:
  Installed: 3.18.5-0ubuntu0.3
  Candidate: 3.18.5-0ubuntu0.3

Status changed to 'Confirmed' because the bug affects multiple users.

Ubuntu :: 16.04.3
gnome-screensaver :: 3.6.1-7ubuntu4
libglib2.0-0:i386 :: 2.48.2-0ubuntu1

Another example:
org.gnome.ScreenSaver[1963]: (gnome-screensaver:2131): GLib-CRITICAL **: Source ID 4988 was not found when attempting to remove it

Ubuntu 16.04.4 LTS
gnat-gps:amd64/xenial 5.3dfsg-1ubuntu1

Another example:
Before fatal error, IDE message log keeps printing:
Source ID #### was not found when attempting to remove it

The message is emitted by glib: https://gitlab.gnome.org/GNOME/glib/commit/a919be3d39150328874ff647fb2c2be7af3df996

The commit log description is: "gmain: Warn when g_source_remove() fails". So why is it calling g_critical() instead of g_warning()? Obviously, it's not a critical error, if people are able to live with these annoying messages for five years with no obvious ill effects. Critical errors are often routed to /dev/console, and it's clearly inappropriate to escalate these messages that high.

Still pumping out messages to syslog:

Feb 22 07:45:03 R2D2 console-kit-daemon[1505]: GLib-CRITICAL: Source ID 69583 was not found when attempting to remove it
Feb 22 07:45:03 R2D2 console-kit-daemon[1505]: GLib-CRITICAL: Source ID 69598 was not found when attempting to remove it
Feb 22 07:45:03 R2D2 console-kit-daemon[1505]: GLib-CRITICAL: Source ID 69595 was not found when attempting to remove it
Feb 22 07:45:04 R2D2 console-kit-daemon[1505]: GLib-CRITICAL: Source ID 69605 was not found when attempting to remove it

Bug is over 5 years old. I have my suspicions that this will never get fixed.
