-- Information about the crash:
Appears to run in list of processes but messes up the logo in taskbar and does not respond to mouse or anything.

No other components (like kmail, kontact, etc.) seem to crash in this way.

The crash can be reproduced every time.

 -- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
