Bug 402642

Application: plasmashell (5.12.6)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-29-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
When you transfer a file from the training preview folder on the desktop to the root folder, the plasma does not occur! THIS IS REPEATED CONSTANTLY! TESTED ON MULTIPLE DIFFERENT COMPUTERS!

- Unusual behavior I noticed:
When you transfer a file from the training preview folder on the desktop to the root folder, the plasma does not occur! THIS IS REPEATED CONSTANTLY! TESTED ON MULTIPLE DIFFERENT COMPUTERS!

- Custom settings of the application:
Default

The crash can be reproduced every time.

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