[Kolab-devel] [issue4837] Kontact startup crash with korganizerplugin as active plugin

[aheinecke]

Shown to me by another user.

He started Kontact -> it loaded -> Korganizer Crash (backtrace attached)
This was reproducable and Kontact could no longer be started.

Changing:
ActivePlugin=kontact_korganizerplugin
to
ActivePlugin=kontact_kmailplugin

Made Kontact start again. You could switch to korganizer everything was normal.
Changing the active Part/Restarting Kontact made the problem appear again.

We were able to track it down to the Birthday ressource. If this was enabled it
crashed otherwise not.

On a second Kontact with the same Addressbooks activated and a Birthday
Ressource and korganizerplugin for startup this crash could not be reproduced.

I see this bug as urgent because it has the potential to make kontact unusable
until you manually modify configuration files.
