Application: kontact (4.10.2)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
I started Kontact and just got past the Akregator restore session dialogue.

- Unusual behavior I noticed:
Kontact was running extremely slowly, taking minutes to startup or to react to clicks. I.e. I would guess that it took about 5 minutes to start. Then it displayed an Akregator restore session dialogue and the mouse cursor was the busy icon. Clicking anywhere on that dialogue would take another few minutes for Kontact to react. When I tried to open a mail folder, Kontact would also take minutes to show the contents. Same goes for messages. I was also able to start multiple instances of Kontact at once, which normally is not possible.

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