What I was doing when the application crashed:
Hi there,

Unfortunately I haven't been able to reproduce this, but the bug reporter said it was useful and I can tell you what I was doing:

I was cleaning up some of the extra windows I had open. I had 4 Kate windows (relatively small) which were grouped in the taskbar. I clicked on the group to see the entries, and then meaning to right click one of them, I accidentally left clicked and dragged. As I let go, plasma seemed to crash and up came the bug reporter.
