Description Sean 2013-07-29 04:17:00 UTC 
Application: plasma-desktop (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-26-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed: Dragging widget "Binary Clock" to desktop. Error earlier in report: Crash does repeat once actions were mocked.

- Unusual behavior I noticed: Animation of "Binary Clock" behind mouse seemed to have frozen, mouse had red circle with / . Esc gave crash report

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

New crash information added by DrKonqi

plasma-desktop (4.10.5) on KDE Platform 4.10.5 using Qt 4.8.4

Dragging an Analog Clock widget onto the desktop.  Existing widgets on the desktop:

- 1 x other analog clock
- RAM monitor
- CPU monitor
- Network monitor
