-- Information about the crash:
- What I was doing when the application crashed:
General usage: office, or video watching, or browsing, or nothing
- Unusual behavior I noticed:
Monitor goes to sleep regardless of being active and having sleep turned off.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
