Application: akregator (1.6.6)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.3
Operating System: Linux 3.1.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
I started akregator for the first time, with my old feed information from KDE3 still present in .kde.  Kde4's akregator just crashes on startup using it.  Let me know if you want a copy of the feed into and I'll attach it.

Even if the feed data has a problem, it shoudn't just crash, but make some effort to tell you what problem and which feed so that I could try to fix it without losing several years worth of marked article archives.

The crash can be reproduced every time.

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