compiz crashed with SIGSEGV in g_closure_invoke()

[Roy Gilby]

An error message appeared indicating that Compiz had crashed. The message appeared immediately after login. I don't know whether Compiz crashed during the previous "shutdown -h now", or whether Compiz crashed during start-up or login. There was no visible indication that COmpiz had crashed other than the apport message.
