Application: akonadi_nepomuk_calendar_feeder (0.1)
KDE Platform Version: 4.5.80 (4.6 Beta1)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-rc3-git6-9-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I hit alt-F2, started typing Akonadi (to restart it because it also crashed) and dang, there was my third 'crash report assistant' screen ;-)

As the backtrace is good according to the assistant I hope this helps you fix it. I can't reliably reproduce it but crashes are quite frequent...

The crash can be reproduced some of the time.

-- Backtrace:
Application: Akonadi Agent (akonadi_nepomuk_calendar_feeder), signal: Segmentation fault
