Application: kontact (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

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

Kontact crashes frequently.  Sometimes, it is immediately after startup, but if it starts up successfully, the crash is usually after I do "something".  For example, if I open another email, it would occassionally freeze for a few seconds before crashing.  The same thing happens if I press a shortcut key like "Delete".  If I leave it open in the background it seems to be fine, but will also crash eventually.

It doesn't happen everytime.  But it happens frequent enough that it is almost impossible to work through 20 new email without crashing once.

Something else I've noticed that may be relevant, is that the Akonadi tray successfully downloads my email in the background.  But occassionally it will tell me that it was unsuccessful and I should enter a new password.  Though, it may also be a problem my be with my ISP, the internet occassionally fades away for a minute or two.

The crash can be reproduced some of the time.
