gala crashed with SIGSEGV in send_frame_messages_timeout()

[Sergey Peshkov]

This happens periodically at random moments in time, I can't figure out what actually is causing it. But as I remember the last thing I did before Gala crashed was using Chrome and typing some info into textbox, then everything freezed for like 15 seconds and the Apport window appeared.

BTW, forget to mention I'm using Freya Beta 2, but I've experienced this on Freya Beta 1 also.

I've also experienced this bug when switching keyboard layout via Ctrl-Space (that's strange, but I didn't do anything except that, and it froze just right after I changed the layout).
