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

Unplugged my laptop from the power adapter, thereby switching to battery power.  Presumably KNotify was going to tell me so when it crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
