Bug 269138

Application: akregator (1.6.6)
KDE Platform Version: 4.6.1 (4.6.1) "release 390"
Qt Version: 4.7.2
Operating System: Linux 2.6.37.1-1.2-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Akregator started normally, updated all four feeds. After that I wanted to click on one of the feeds to read the articles, what causes app to crash.
- Unusual behavior I noticed:
Normal operating of Akregator until one of the feeds is checked by mouse click. Other feeds are working correctly and are not causing Akregator crashes.
- Custom settings of the application:
Akregator updates feeds after starting it and in every five minutes.

The crash can be reproduced every time.

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