-- Information about the crash:
- What I was doing when the application crashed:
I was trying different layouts for displaying mail previews and selected "Display to the Right of the message list" or whatever it is.  I hit apply and it promptly crashed.  Ubuntu 11.04 (work machine came with that; gutted Unity and installed KDE 4.7) and their repos.

-- Backtrace:
