Description Alex Wright 2012-02-19 13:29:38 UTC

Application: kontact (4.8.0)
KDE Platform Version: 4.8.00 (4.8.0 (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.2.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.0.3"

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

The first launch of Kontact crashes immediately.
The next launch works, but fails to synchronise email properly.
The next launch crashes.
Rinse, repeat!

Kontact is closed with the quit menu item between launches.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

Unfortunately, the backtrace is not helpful.
If you can reproduce this bug, please install the debug package and paste a better one.

It turned out that it was some problem with Akonadi. Rebooting the machine fixed the problem. It has not reoccurred.
