Application: akregator (1.6.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-gentoo-r1 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I was not using Akregator actively, so maybe it crashed because of downloading feeds automatically in the background.

Previous to this crash I could not start Akregator for weeks (process was created but used 1 CPU fully without showing the user interface) until I found out that some bogus feed items could cause this.
I deleted feedlistbackup.mk4 and archiveindex.mk4 and afterwards I could start Akregator again.

The crash can be reproduced some of the time.

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