Bug 241635

Application: akregator (1.6.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Akregator showed an old article as new in the "All feeds" group. Even though I clicked on it,
it kept being shown as 'new' (not 'unread', but 'new'). I looked at the others that where new. I
switched to another feed. When I got back to "All feeds", Akregator crashed.

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