Bug 229440

Application: akonadi_kcal_resource (0.1)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-174.2.22.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
I've configured akonadi with 2 remote files calendars, one is read-only and the other is writable.

Every 5 five minutes akonadi segfaults.

The crash can be reproduced every time.

 -- Backtrace:
Application: Akonadi Resource (akonadi_kcal_resource), signal: Segmentation fault
