compiz crashed with SIGSEGV in g_main_context_dispatch() from ... from CcpScreen::timeout()

[Penda Houzangbe]

I don't know exactly what causes this crash (I don't think I can reproduce it whenever I want), it happens quite often, apparently randomly, but I suspect it may be when I run many applications at the same time (I use a standard netbook, maybe the load is too heavy for it running compiz plus many other processes). Unity then restarts, no other application crashes, they're only restored on the 1st viewport instead of keeping their orginal position. Hope that helps.. Sorry for the lack of precision.
