I can somewhat consistently (4/5) cause a crash on a fresh install of 8.04.1 64-bit install with fglrx, compiz normal and dual screens (via Option "DesktopSetup" "horizontal") with an x1950 Pro.

To reproduce:
1. Start a fresh graphical session with the above
2. Open firefox
3. Open a YouTube video
4. While that video is playing open a new tab
5. Start a second YouTube video in the new tab
6. Open a new firefox window
7. Move the new firefox window onto the second display
8. Open a YouTube video in the new window on the second screen
9. With all three videos playing, close the one on the primary display (it has two tabs)
10. When prompted select close tabs to confirm
11. Xorg crashes either completely (thus restarting gdm) or it takes the displays down (leaving the contents of the session running) and spins, usually unable to be killed even with "sudo pkill -9 Xorg"

I cannot reproduce the issue with compiz disabled.

See attached stacktrace. Thanks.
