Application: plasmashell (5.12.6)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-33-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I clicked on a wifi network to connect to it from the botton menu bar.But I had mistakenly selected it so I clicked on another one (before the system finished connecting to the previous one) Then I again clicked on the 1st wifi (note that the system had not finished connecting to the first wireless by this time). This caused the shell to crash.

I tried to repeat this multiple times and the shell crashes every time I rapidly click multiple wireless networks when they are still in the process of connecting

The crash can be reproduced every time.

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