Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-22-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I created two shortcuts for opening clipboard and network. 
I open one of them using the shortcut. 
I hit esc to make the popup go away. 
The popup is replaced by the "hidden icons" popup.
I hit the other shortcut to open the other popup. 
Plasma crashes.

The crash can be reproduced every time.

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