Bug 320104

Application: choqok (1.3)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-43-generic x86_64
Distribution: Linux Mint 13 Maya

-- Information about the crash:
Choqok sometimes crash in the background, probably while trying to refresh informations.

I am using the latest version from the git repository. I've seen similar bugs marked as fixed, so I don't know if the git repository is out of date, or if it is a new bug.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Choqok (choqok), signal: Segmentation fault
