Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Linux Mint 13 Maya

-- Information about the crash:
- What I was doing when the application crashed:
I was using the desktop as normal. Web browsing, IRC, skype, and so forth.  
This type of crash happens nearly every day. It happens most commonly overnight, when I allow the system to idle, however it does happen whilst using the desktop, without any warning or system slowdown.

- Unusual behavior I noticed:
None. Happens seemingly at random, when system has been running for extended periods of time.  System can either be idle or in use.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
