compiz crashed with SIGSEGV in nux::WindowThread::GetTimerHandler()

[Martin Constantino–Bodin]

Hi,

This bug appears right after a system upgrade to Quantal.
It has been automatically detected by Apport, but I did not see any graphical evidence of any disfunctionning (expect of course the message form Apport). I thus know very little of it, but I' m willing to help if you need any further information. Just ask!

You may be interested by the informations collected by Apport while looking for this other bug, it can be linked: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1059254

Hoping it can help,
Martin.
