-- Information about the crash:
- What I was doing when the application crashed:
I was trying to setup my dock using this Now Dock widgit and it randomly crashed
- Custom settings of the application:
As said above I was using a Now Dock panel, and trying to add the Now Dock widgit. So whatever the crash was, it had to do with the dock.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
