Application: plasmashell (5.5.5)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.1.15-gentoo-r1 x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
- What I was doing when the application crashed:
Attempting to move plasmoid from upper right corner of desktop to lower left corner. There happened to be a window between the source and destination points.

- Unusual behavior I noticed:

I have three displays. I tried moving a plasmoid from the leftmost display to the rightmost display, and it disappeared, though the plasmoid counter indicated it was still...somewhere.

Also, for the life of me, I cannot seem to get a panel to *stay* on the right edge of this rightmost display. Log out and back in, and it reappears on the right edge of my leftmost display.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
