Application: kontact (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Inställningar -> Anpassa kmail (sv)
Settings -> kmail settings (~en)

- Unusual behavior I noticed:
Reason I wanted to enter the settings menu was that nothing happens...
Clicking on a mailbox and it get stuck on "Retrieving mailbox contents" (~en) 
I have a huge amount of emails
My suspision is that indexing of those have started...
But if so it is very ineffective
  akonadiserver 11% CPU
  mysqld 11%
  kontact 8%
  dbus-daemon 1%
  virtuoso_t ...
  akonadi_nepomuk_feeder ...
  akonadi_control ...
and almost no disk access...!!!

- Custom settings of the application:
Search indexing has not worked before

The crash can be reproduced every time.

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