Version:            (using Devel)
Installed from:    Compiled sources

I've seen the crash below while running Kontact 4.1.86 (using unofficial Debian packages from kde42.debian.net at version 4:4.1.86+svn902265-0r1). I'm not exactly sure which chain of events lead to the crash and hence I can't reproduce it.

The symptoms I observed prior to the crash were that the Akonadi resource in the Calendar component was unavailable. I was notified of this by a pop-up dialog (the exact wording of which I can't remember) after writing several emails. I think the resource must have been available at the time I started Kontact because I think I saw my appointments in the Summary view.

I restarted Kontact and the check next to the Akonadi sub-resource ("akonadi_ical_resource_0") was indeed gone. I restarted Kontact once again and it crashed (see below). I restarted Kontact yet again and things were back to normal. I didn't make any significant changes to the configuration during these last three steps.

The backtrace of the crash is as follows:

Application: Kontact (kontact), signal SIGSEGV
