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

[C de-Avillez]

Suddenly, while trying to switch windows. Since there are 8 other bugs on SEGV on IsInsideLayoutCycle(), ranging from Invalid to FixReleased, I am opening a new one, hoping that apport processing will give me a stacktrace I can follow.

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

Occurred to me when running compiz --replace to get a newly-installed lens running.

Thanks for the bug report. Is that still an issue for you Ubuntu 12.04 with all updates applied? Can you please test that and let us know?
