Application: kontact (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.10.5 x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
I had been (and still am) getting Bad Request from the google calendar conduit and so I backed up the events into an ical file, deleted the calendar, re-added it and then imported the ical file.  It reported that the ical was imported correctly.

I then went to kmail and noticed that folder list was corrupted leaving only one icon.  I clicked on the icon and kontact crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
