Description Con Kolivas 2016-08-05 21:45:05 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.7.0-ck1 x86_64
Distribution: Ubuntu 16.04.1 LTS

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

I have a 4k monitor (which is seen as 2 separate screens) so I have 2 taskbars created since I can't create a taskbar that spans both screens. One for the left half and one for the right half. After a return from suspend to ram, I usually have to restart plasmashell since I lose the second taskbar. This time the taskbars stayed intact but switched to the left screen only (after jumping around from one screen to another for a while). When this happens I usually have to drag the task bars around till I position them in the right place. This time while dragging one of them it crashed.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Con Kolivas 2016-08-06 21:49:45 UTC
