           Summary: akregator crash on startup
           Product: akregator
           Version: 1.6.6
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: nick at leverton.org


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
