Application: plasma-desktop (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

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

This happens pretty randomly actually. I cannot pinpoint which action provokes it.
I'm usually rapidly switching between desktops and activities. This time I had switched and was changing properties in Jitsi (a java application for chatting).

Sorry I do not have more information :\
