Bug 383458

Summary: Plasma crashes while repositioning plasmoid (use of network assets) in a dual monitor, automatic hiding taskbar asset.

Sentry Crash Report:

Description stakanov.s 2017-08-13 14:09:04 UTC 
Application: plasmashell (5.8.7)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.79-4-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:
Shifting the plasmoid of network activity from the right side to the left downer corner. The taskbar popped up and down as I came near. I did not release the plasmoid which did then "vanish" and did not(!) appear on the taskbar either. 

- Unusual behavior I noticed:
screen flickers and goes black. Plasma crashes and reloads. The formerly present and set plasmoid crashes too and vanishes. 

- Custom settings of the application:

dual monitor (one 16:9 and one traditional (5:9?) in a dual monitor setup. The plasmoid was NOT shifted from one monitor to the other. No primary monitor set. 
ATI graphics with OSS driver that shows some issues with kaffeine (flicker when fullscreen). Otherwise the plasmoids where unlocked. The taskbar (that may be at the origin) was set to autohide)

The crash can be reproduced sometimes.

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