Bug 232112

Application: kontact (4.4.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-17-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
One feed in my Akregator shows -1 unread entries in the left hand pane when no unread entries exist. A new entry appeared in this feed and the -1 was increased to 0. On trying to open the unread entry by clicking on it in the right hand pane, kontact crashed.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
