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

search chro(mium) in launcher, grab icon, drag it to the "quick lauch" area beside the launcher, wildliy swing it about left and right to find a proper position to drop it while stuff beneath rearranges itself. There are currently 2 other icons in my quick launch area, konsole and firefox.

This is after the first login into the new kde 5 Kubuntu 15.04 desktop. I haven't tested if this is reproduceable after logging out and back in.

The crash can be reproduced every time.

Reproducible: Always
