Bug 322938

Application: kontact (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.9.10-100.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

-- Information about the crash:
- What I was doing when the application crashed:
I've just added and syncronized a Google Calendar on the "Calendar" section of Kontact. I the returned to the "Mail" section and got, in the preferred folders panel, two different bookmarks: one named "Search" and one with an "Inbox" I did not had previously in the preferred folders.

- Unusual behavior I noticed:
A lot of icons and text labels of folders were missing, and after a couple of second the application crashed.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
