Bug 236801

Application: akregator (1.6.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Akregator will be running unobtrusively in the background, and then crash.  Nothing specific triggers it that I can discern, and the span of time from restart to the next crash is variable and unpredictable. 

The crash can be reproduced every time.

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