Xorg crashed with SIGABRT in MakeAtom()

[Stuart Langridge]

Crash back to login screen for no apparent reason. I was watching a video on vimeo and compiling something in qtcreator at the time.

As a data point, at some point earlier (don't know when) tooltips in Firefox had stopped showing up when mousing over HTML elements with a title attribute. I don't know if that is related.
