Bug 256515

Application: akregator (1.6.5)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I was browsing through "unread" entries, one wouldn't show (remained unread, and also had a duplicate in the list) and the left panel showed -1 unread entries (were it should have shown 1, or 2, or at least 0...). When clicking on another directory and then back on the main directory (which I do every time I want to clear all read entries in the list), akregator crashed. This has been happening a lot, but I'm not sure how to reproduce it...
Also, when I restart akregator, the buggy entry is marked as read.
- Custom settings of the application:
The "unread" filter is always on and entries are marked as read as soon as I open them.

The crash can be reproduced some of the time.

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