Description matt 2009-07-24 17:41:34 UTC 
Version:           4.2.2 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.28-14-generic

I added some entry to my calendar, and while archiving (and possibly other things), korganizer and kontact both segv

Periodically korganizer and kontact crash since adding this entry, and they don't crash when I uncheck this particular calendar.  When I have the calendar enabled and run archiving it is guaranteed to crash.

Application: KOrganizer (korganizer), signal SIGSEGV

Comment 1 Dario Andres 2009-07-24 19:56:15 UTC 
As you can reproduce the crash oftenly, can you install the "kdepimlibs-dbg" and "kdepim-dbg" packages in order to get a complete backtrace the next time to paste it here? Thanks
Comment 2 Jonathan Thomas 2009-07-24 22:19:04 UTC 
This bug was also reported to us downstream at Launchpad. It turned out to be a duplicate of another bug that nobody got around to forwarding here...

Anyway, the bug, https://launchpad.net/bugs/384983 has an almost-complete backtrace which is just missing a few lines from the KIO libs. It would be nice if you could install kdepim-dbg and get a new backtrace, preferrably with KDE 4.2.4 if possible: (http://www.kubuntu.org/news/kde-4.2.4)

Here's the backtrace.
