Bug 400555

Application: kdeinit5 (18.08.2)

Qt Version: 5.11.2
Frameworks Version: 5.51.0
Operating System: Linux 4.18.16-arch1-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
The "Empty Recycle Bin" button is not responding, so I used the trash-empty(trash-cli) command and then. . .

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
