Comment 40 for bug 131679

Just so people know (and sorry for the spam) every single duplicate of this bug is probably actually a completely different problem. Crashing in doPoll just means something went weird in compiz that didn't trip it up until the next time it went through this function. I'm not sure how all of these bugs ended up as duplicates (I know many/most were done automatically by apport) but we should probably at least have a separate bug for each action someone was performing when this happened.

Also, unless someone finds the right magic to harden compiz to such problems there is probably no good way to debug this problem since the corruption of compiz state almost certainly happens at some early point that could be quite some time ago.
