Bug 331119

Application: akregator (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.5
Operating System: Linux 3.12.8-200.fc19.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I was reading some feeds, finished the outstanding articles for one and was ready click on the next one I wanted to read.  I noticed the feed I was reading showed something like 773 unread articles (though there was only  one in the article list).  Other feeds showed equally crazy article counts.  I hit Ctrl-Q, then tried to restart Akregator from the command line.  It failed with messages shown below:
