Thank you for your report!

However, processing it in order to get sufficient information for the

might be caused by some outdated packages which were installed on your system

Affects me on Ubuntu 13.10 upgraded from 13.04.

This thing hangs system,

I Have this Problem in ubuntu 14.04 with gnome 3.12

Thank you for reporting this bug to Ubuntu. raring reached EOL on Jan 27, 2014.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

Please feel free to report any other bugs you may find.

Still affects 14.04.

Maarten and Kaname, please file new bugs, the stacktrace on this bug is invalid and the actual crash message is very generic so it may not even be the same bug you are seeing.

still affects 14.10-RC with gnome3.14

Still here in 2016.

crash on startup

Again, today. I was using tweak-tool to change the gtk+ theme.

I don't recall doing anything special.

After reboot and some applications startup system hung for 10 seconds. After that this system error message appeared and system was back to normal.

Same here in Ubuntu GNOME 16.04 with gnome 3.20.3

Same here in Ubuntu Gnome with gnome 3.20.3

Same here under Ubuntu 16.04 and Gnome 3.20.4
Stuck the whole interface for one minute when I've tried to move an icon on the favbar. Freezed again for 30s or 1mn when I've started an application just after this. Freeze ended by a Gnome dirty restart with all workspaces windows on the same screen, I did Alt+F2 and "r" to restart properly. Now everything seems ok but it's a weird bug. Hard for noobs like me to understand the cause at first sight.

Happened to me a bit ago also with

Description: Ubuntu 16.04.2 LTS

gnome-shell:
