gnome-appearance-properties attempting to access noexistent directory

Thank you for your bug. Could you get a stacktrace while it's hanging?

Thank you for your bug report. Could you get a stacktrace while it's hanging?

Here is the stack trace. The program hangs at:

stat("/home/guests/swo", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
open("/home/guests/.hidden", O_RDONLY) = -1 ENOENT (No such file or directory)
stat("/home/guests/swo", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
stat("/home/guests", {st_mode=S_IFDIR|0755, st_size=12288, ...}) = 0
open("/home/.hidden", O_RDONLY) ****here**** = -1 ENOENT (No such file or directory)

Thanks!

could you get a stracktrace using gdb rather than a strace? install gnome-control-center-dbgsym libglib2.0-0-dbgsym libgtk2.0-0-dbgsym and use gdb as explained on https://wiki.ubuntu.com/Backtrace, you can use ctrl-C to get a prompt under gdb while the software is hanging

Here is the gdb backtrace.

Could you install libgtk2.0-0-dbgsym and get a new stracktrace? Does doing a stat on the same filenames on a command line hangs too? Do you get the same issue using other applications?

Hi,

Actually, libgtk2.0-0-dbgsym was already installed when I collected the stacktrace. I looked though the stacktrace and yes, I noticed that there were no debug symbols for the backtrace through the gtk functions. However, I don't know how to remedy this.

To answer your other questions: yes stat /home/.hidden hangs. There are other applications that hang also. For instance users-admin hangs while trying to access /home/syslog.

the lack of symbols might be due to a version mismatch between libgtk2.0-0-dbgsym and libgtk2.0-0, stating for those files to know if they are there might be required so it's not clear that's a gtk bug, you should rather fix your installation to not hang when something try to stat a file there

stat of any file in the mounted share point (i.e. /home) that does not exist hangs. Stat of the same non-existent file on Ubuntu 7.10 returns immediately.

the 8.04 version of autofs is 4.1.4+debian-2.1ubuntu1
the 7.10 version of autofs is 4.1.4+debian-1

here is my auto.master file:
/home /etc/auto.home --timeout=15

here is my auto.home file
* -intr,soft,nosuid,rsize=8192,wsize=8192,udp duos:/home/&

These files are identical on the 7.10 and 8.04 installs
A wireshark trace on the 8.04 installation shows an immediate return of the NFSerror ENOENT (no such file or directory) so the issue is not with the network or network layer.

*********
While I do not understand why a bunch of gnome applications are trying to access files like /home/.hidden and /home/syslog I do not believe this is a gnome or gtk bug.
I am going to open a new bug with autofs

Thanks

closing this task since that's not a GNOME bug
