I don't know the cause of this crash, but after restarting compiz by hand it crashed again several times before I was finally able to get my session back on its feet.

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

[Alberto Salvia Novella (es20490446e)]

This bug needs now to be notified to the upstream developers of Debian (https://wiki.ubuntu.com/Bugs/HowToTriage#Forwarding_upstream).

Once this has been done, it will be ready to be worked on by a developer.

[Alberto Salvia Novella (es20490446e)]

Sorry, it appears that Compiz is tracked here in Launchpad; so no need to report this to Debian.

[Christopher Townsend (townsend)]

This bug is reported on a rather old version in the Saucy cycle of Unity/Compiz. Is this crash still occurring for people? The bug heat is pretty low and I haven't noticed any duplicate bugs with this signature come through lately.
