Application: kontact (4.9.1)
KDE Platform Version: 4.9.1
Qt Version: 4.8.3
Operating System: Linux 3.5.4-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:

Kontact was still starting up (apparently getting folder information from Akonadi), but I entered some text into the folder search box (left upper corner) already. Kontact crashed almost immediately.

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