Caught another one after unlocking the screen, this time with a slightly different backtrace: [ 18104.137] [mi] EQ overflowing. The server is probably stuck in an infinite loop.

Like with Bug 596022, when a new login screen came up, the Fedora logo and my .face were garbled. Killing X again solved this. Oddly, all the current bugs I've seen in X (this, segfaults, aborts) have been at screen blanking time, or when unlocking the screen (presumably having blanked).
Not seen any crashes since 2010-07-20 with xorg-x11-drv-intel-2.12.0-1.fc13.x86_64, will close soon as fixed with this version if things stay stable.
