Application: plasma-desktop (4.11.97)
KDE Platform Version: 4.12.0
Qt Version: 4.8.4
Operating System: Linux 3.12.0-7-generic x86_64
Distribution: Ubuntu Trusty Tahr (development branch)

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

Started to customize a new install to my preferences, when plasma crashed:
0.) had some windows open on a virtual desktop, switched to an empty one
1.) moved the panel from bottom to top
2.) adjusted the height of the panel
3.) moved activities button from left to right (placed it left to systemtray)
4.) selected "add widgets"
5.) added icon tasks left to regular tasks applet 
6.) removed regular task manager 
=> plasma froze and crashed after some input

-- Backtrace (complete, with all debug symbols installed):
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
