Application: plasmashell (5.16.5)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-24-generic x86_64
Distribution: Ubuntu 19.10

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

1. Open Google Chrome
2. Select URL from link-tab. For example: github.com/lattera/glibc/blob/master/csu/libc-start.c
3. Drag
4. Press WIN+D (KWin -> Показать рабочий стол (Show desktop?))
5. Drop
6. Click to Создать ссылку (Ctrl+Shift) (Create link (Ctrl+Shift)?)
And Plasma-desktop will reboot.
For debug i installed libglib2.0-dev, libkf5kiocore5, plasma-desktop-dev, plasma-kdevelop

The crash can be reproduced every time.
