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

I was brownsing in firefox and decided to start my VPN, so I clickd on the Network manager icon next to the clock, I selected the VPN that I have added, clickd on connect and it crashed.

I always have to type my password (I wanted it this way), the password prompt screen didn't shoow up

system recovered and I connected normally as always.. 
(uname -a= 5.2.11-arch1-1-ARCH #1 SMP PREEMPT Thu Aug 29 08:09:36 UTC 2019 x86_64 GNU/Linux)

The crash does not seem to be reproducible.

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