Thanks; re-testing xorg-edgers is helpful but this is almost certainly a kernel bug. xorg-edgers doesn't carry kernel updates, so I wouldn't expect it'd solve this. Instead, download and boot a new daily cd, then run 'apport-collect 681054' to update the logs.
This is kind of a borderline High/Medium importance... on the one hand it is a severe issue, on the other it appears to affect only a single person. I'll bump it back to high for now.
