-- Information about the crash:
The plasma workspaces crashes when using the quicklauncher plasmoid.

Steps to reproduce:
1.) Add Quicklauncher plasmoid to desktop
2.) Drag existing application launcher outside of the quicklauncher and then back in
3.) Drop the existing application launcher back on the quicklauncher
4.) Crash, plasma workspace is re-created

The crash can be reproduced every time.

 -- Backtrace:
