is looks like it crashes after i do the following.
1. start korganizer.
2. refresh a local calendar (calendar resource within directory, one file per event).
3. then click any day to mark or add a new event.

Comment 2 Christophe Marin 2011-05-05 22:13:32 UTC

from bug 272052 

-- Information about the crash:
I added a GroupDAV Calendar to Kontact (activated “save after every change”).
GroupDAV server is “Stylite's EGroupware Community Version 1.8.001”, protocol
is https.

Existent Events in database was fetched and shown correctly. I added a new
Event and confirmed the save dialog. Kontact crashed. Event was not transferred
to the server. Crash was immediately after confirming the save dialog.

This kind of crash happend two times. Since starting this report, every try to
reproduce the error was unsuccessful (that means that everthing works now). :)

What may be intresting:
When the bug not appears, before sending the new event to my server, Kontact
told me that the ssl-certificate of my server is not secure. I told Kontact to
accept it. This repeats two more times, even I tell kontact to accept it
permanently (!). Then, Kontact sends the event. Maybe the “unsecure”
ssl-certificate is part of the cause.

The crash can be reproduced some of the time.
