Description stepik-2003 2021-01-05 11:54:29 UTC

Frameworks Version: 5.77.0
Operating System: Linux 5.4.0-59-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.20

-- Information about the crash:
- What I was doing when the application crashed:
1. I click on the device line, hold down the button and drag the line
2. Dolphin crashed

P.S. I did it once, I managed to move one device for the very first time. However, after that, any attempt is made to crash

The crash can be reproduced every time.

-- Backtrace:
