Operating System: Linux 3.2.0-32-generic-pae i686
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Crashed while typing in a new name on the face.  It occured while hovering over the face area that the name is suppose to be typed in.  No warning, just closed.

The crash can be reproduced some of the time.
