Application: akregator (1.6.6)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- Unusual behavior I noticed: akregator counts on one  or more feed to negative values e.g. -1 when all msg on read status. Retrieving feeds shifts to positive value -(n) again until reading all messages. Sometime later it crashed mostly when minimized or hidden

The crash can be reproduced every time.

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