Comment 3 for bug 517794

This happened again, and I was able to get some info from a different TTY.

Here's the relevant part from /var/log/messages - compiz crashes.

Feb 24 13:17:06 fridge kernel: [349959.691938] compiz.real[22928]: segfault at 5 ip 08055c3c sp bfc0a410 error 4 in compiz.real[8048000+34000]

This bug is actually intermittent - it does not always happen on first login after all. Zapping X sometimes causes it; first login sometimes works fine. Last time that this happened, ctrl alt bksp was not enough to recover from it; I had to completely reboot the machine. I didn't capture Xorg.log from that startup, but my current one is attached.
