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

Package: nautilus 1:3.10.1-0ubuntu8
ProcCmdline: nautilus

The stack trace here seems corrupted but the errors.ubuntu.com report that is linking to this bug report [1] shows a proper stack trace.

This indicates the problem is when a warning dialog pops up on startup due to either the home directory or desktop directory not existing. Some following code then assumes this dialog is a file browser window and hits an exception.

I tried to reproduce this locally by deleting my Desktop folder / replacing it with a file but then it just reverts to using the home directory. The error reports don't give an indication on what users are doing to trigger this.

I can reproduce the crash by modifying nautilus to show the dialog always on startup.

Found a way to reproduce, updated description.

Hello Pedro, or anyone else affected,

Accepted nautilus into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/nautilus/1:3.10.1-0ubuntu9 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[ubuntu 14.04-64bit on virtualbox.]
confirmed Observed result:
You arrive at the users desktop but background icons are not shown.
A blank dialog pops up momentarily then a crash report dialog.
The blank dialog periodically pops up again (as nautilus attempts to restart).

[enable trusty-proposed & install nautilus.]
$ apt-cache policy nautilus

exit & logout

[login testuser]
pop up "Oops! Something went wrong." dialog. (does not repeat momentarily.)
---------------------------------------------
Unable to create a required folder. Please create the following folder, or set permissions such that it can be created:
/home/testuser/.config/nautilus}
---------------------------------------------

click "ok" button. --> pop up dialog cleare.
start nautilus. --> no problem.
open terminal & delete .config/nautilus
relogin testuser --> auto created ~/.config/nautilus directory & no pop up dialog.

Is this result correct?

Thanks katsu! That looks correct to me. Please update the tags.

The verification of the Stable Release Update for nautilus has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

errors.ubuntu.com has indicated the following error reports came after this update so it has not been fully rolled out. I am investigating if this change has caused them.

The error reports seem to be random memory corruption. I'm not sure that this SRU is causing these - it may be that there is an existing corruption issue that causes different stack traces each time it occurs. Looking at https://errors.ubuntu.com/?release=Ubuntu%2014.04&package=nautilus&period=day seems to indicate this might be the case.

https://errors.ubuntu.com/api/1.0/package-rate-of-crashes/?format=json&release=Ubuntu%2014.04&package=nautilus&old_version=1%3A3.10.1-0ubuntu8&new_version=1%3A3.10.1-0ubuntu9&date=20140505

This has the rate of crashes between the two package versions but it only indicates that there has not been an increase, not the actual difference in quantities.

I'm okay with manually setting the phased-update-percentage of this to 100%.
