Bug 282971

Application: konversation (1.3.1)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 2.6.40.4-5.fc15.x86_64 x86_64
Distribution: "Fedora release 15 (Lovelock)"

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

Waking laptop up from sleep when Konversation appeared to segfault.

- Unusual behavior I noticed:

High swap usage paired with high CPU usage. Nepomuk and knotify both were using quite a few cpu cycles in this instance.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
