Application: kontact (4.4.7)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic i686
Distribution: Ubuntu 10.10

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

Due to a timing accident I managed to press the "fetch all email" button from the kmail toolbar right before it was replaced by the akregator toolbar (akregator was already loaded in the main view). Due to the nature of this bug, I didn't manage to try again.

The crash can be reproduced some of the time.
