Application: plasmashell (5.7.4)
 (Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.4.6-gentoo x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
- What I was doing when the application crashed:
Removing extra panels and rearranging the ones I was keeping. I began with three  (possibly four, but I can't find that one since removing the third monitor), removed the one on the left edge of the center display, removed the one on the bottom edge of the center display, and attempted to move the panel from the top edge of the center display to the bottom edge of the center display.

The panel settings control bar got stuck in the middle of the screen and refused to be moved or otherwise interacted with. Other applications continued normally. Then, plasmashell crash. On relaunch, the panel on the left edge of the screen had returned, though the panel at the bottom edge of the screen was replaced with the one I had been attempting to move to there from the top of the screen.

- Unusual behavior I noticed:
Panel settings control bar got stuck in the center of the display until it crashed.

The crash can be reproduced sometimes.

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