Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.3.3-4-default x86_64
Distribution: "openSUSE Tumbleweed (20160117) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Removing panel that was on the wrong screen (leftmost), adding panel to central screen.
- Unusual behavior I noticed:
Panel is always re-created on leftmost screen, wrong size. It also overlaps onto the central screen. When a panel is created on the central screen, the panel is the wrong size and overlaps onto the leftmost screen.  The backgrounds of both the leftmost screen and the central screen (of 3) are the wrong size horizontally.

The crash can be reproduced every time.

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