Bug 259881

Application: akregator (1.6.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-26-generic-pae i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
Had a power outage yesterday. Akregator hasn't started since. Sometimes it hangs with a blank window and I have to terminate it. Sometimes it displays the feed tree and attempts to start downloading feed updates before crashing. Sometimes it crashes even before opening the main windows and starts the Crash Reporting Assistant. Is there a corrupted file somewhere? IMO, Akregator should not crash upon reading bad data.

The crash can be reproduced every time.

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