Adam, can you tell us what was going on at the time this happened?
Comment 2 Adam Williamson 2012-02-28 00:49:22 UTC 
Ah, this one. I think the reason it has no explanation is that it coincides with my keyboard suddenly entirely ceasing to work. The system appeared to be running mostly as normal, but I couldn't get keyboard input to work at all in any way.

I don't recall doing anything in particular to trigger it, I was just using the system as usual, which for me mostly entails Evolution, Xchat, and Firefox.
