-- Information about the crash:
- What I was doing when the application crashed:

I had just logged in when I saw the crash notification. Everything seemed to work fine. I tried to attach this info to bug 356411, but the bug-reporting app didn't seem to register that I had attached it.

The crash can be reproduced sometimes.

-- Backtrace:
