[Kolab-devel] [issue4838] Kontact might crash on activating Korganizerplugin

[aheinecke]

Happened to me three times today after activating the Birthday ressource to test
issue4837.

Birthday ressource is active, Korganizer is in Agendaview with a Birthday on
that day. I've read some mails in Kmail, switched to korganizer -> crash.

It's not really reproducable I've just switched the parts for dozens of times
without a crash but as it happend three times today it also does not appear to
be completly random. Maybe attached backtrace helps.

Version 20120322.0d8ab49
