Application: akregator (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Linux Mint 12 Lisa

-- Information about the crash:
- What I was doing when the application crashed:
I would try to mark all items in a section read by right-clicking and then try to read a different article in another section. Akregator would then crash. 
- Unusual behavior I noticed:
The entire operating system became unstable around the same time at least twice although I can't seem to reproduce it now.

The crash can be reproduced some of the time.

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