Description David Zaslavsky 2010-05-14 04:11:18 UTC
Application: akregator (1.6.3)
KDE Platform Version: 4.4.3 (KDE 4.4.3) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
My system shut down suddenly due to a power outage. When I restarted it and ran Akregator, at first it crashed immediately on startup (which I reported as an attachment to bug 116482), then I removed archiveindex.mk4 and tried again and it displayed the main window for about a second, but then crashed again. By trial and error I determined that the crash is related to one particular mk4 file which I presume is corrupted (at least, if I delete this one file, it works fine).

The crash can be reproduced every time.

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

I've put the mk4 file that triggers the crash online (in a tar archive) at http://www.ellipsix.net/ext-tmp/hepph.mk4.tar
