Description Leonardo Donelli 2013-05-16 22:05:01 UTC 
I encountered this bug when trying to replicate bug https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/822993.

How to reproduce:
1) Open nautilus as root: 'gksudo nautilus'
2) Right click on a folder/file owned by normal user -> Properties

Expected result:
 - Properties window

What happens
 - Nautilus crashes with error: ERROR:nautilus-properties-window.c:1836:schedule_owner_change_timeout: assertion failed: (NAUTILUS_IS_FILE (file))

Ubuntu 13.04
Nautilus 1:3.6.3-0ubuntu16
Comment 1 António Fernandes 2013-05-17 09:09:04 UTC 
Thanks for taking the time to report this bug.
Without a stack trace from the crash it's very hard to determine what caused it.
Can you get us a stack trace? Please see http://live.gnome.org/GettingTraces for more information on how to do so. Thanks in advance!
Comment 2 André Klapper 2013-05-17 10:14:29 UTC 
Does this also happen as a normal user?
Comment 3 Leonardo Donelli 2013-05-17 10:29:35 UTC 
No, it doesn't happen as normal user. Maybe the problem is gksudo?

I generated a backtrace, but there are a lot of 'no symbol table info avaiable' messages. I installed only nautilus-dbg, what others *-dbg packages should I install?

Please ignore the previous (double-posted) patches. In addition to this bug, they fix an unrelated bug which has yet to be filed. Meanwhile, here is another patch.

I can confirm that this was happening on 3.10.1 and 3.12.2 as well. This commit https://git.gnome.org/browse/nautilus/commit/?id=f7d1394a03e6d02cd5c67f9c85a142e33f14566f fixes both this issue and https://bugs.launchpad.net/ubuntu-gnome/+bug/1405441
