Description martin.strecker 2016-10-19 06:45:51 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.31-30-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
My laptop is connected to an external monitor. I had put the laptop to sleep. When restarting the laptop, plasma crashes.

- Unusual behavior I noticed:
I do not know any more what is usual and unusual in Plasma. The only thing I can say is that KDE / Plasma has become TOTALLY UNUSABLE. It is impossible to get the system panel back to my primary (= laptop) screen when unplugging the external monitor, which means that I cannot control my laptop any more without using an external monitor. And this even after a reboot without an external monitor. And now, the developers of this system have even been so ingenious as to remove a "create new / default panel" menu item from the desktop menu, and there doesn't seem to be another backdrop to get the system working again. Do you see any other way out than to install another system than KDE? This is basic and critical functionality that has been defective for months, and nobody seems to care.

The crash can be reproduced every time.

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