Bug 388092

Application: dolphin (17.08.3)

Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.6-2-ck-haswell x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Right-clicking on a Dolphin trashcan icon on the side bar and selecting "Emtpy Trash", makes Dolphin crash immediately

The crash can be reproduced every time.

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