Bug Description

Binary package hint: nautilus

Nautilus crashes immediately at start-up (using auto-login) and starts many new nautilus instances.
Stacktrace looks different then bug 403549.
This started after today's updates. Until today I have not seen this crash.

There was no disk in the drive.
The crash happened before I could start anything myself.

Confirming, and setting to HIGH. In my case, I get a very unresponsive gnome, with nautilus spawning off continuously.

Removing librasero-media0 (and removing is dependencies) bypasses the issue. I did not have brasero installed, to begin with.

looks like a libbrasero issue, reassigning and also will send upstream.

I can confirm that indeed removing the libbrasero-media0 allows nautilus to work.
There was a bug #405544 (unable to burn CD or DVD with Brasero with 2.6.31 kernel) that got fixed in the recent version of nautilus.
Maybe they are related, since the offending package with our bug is libbrasero-media0.

Upstream git commit c255543c "Should fix #591826 – nautilus crashed with SIGSEGV in strcmp()" solves the problem for me.

  * debian/patches/012_fix_null_device_crash.patch:
    - Upstream GIT change to not assume that all GVolume's have a

I have the same issue BUT I deleted brasero and it didn't help. Only sudo mv /usr/bin/nautilus /usr/bin/nautilus-backup helped...

well, removing libbrasero-media0 didn't do it for me, LoonyPhoenix's way stopped the constant opening of nautilus instances and the segfaults have become less frequent in the logs. But i cannot use the desktop at all the normal way, i had to sudo nautilus via gnome-do.
