Application: dolphin (16.12.2)

Qt Version: 5.8.0
Frameworks Version: 5.31.0
Operating System: Linux 4.9.11-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

Every time I tried to definitely delete some files in Dolphin, I pressed Shift+Supr on some selected files and Dolphin hanged when a dialog tried to appear. A few seconds later, the whole application closes and Crash Reporting Assistant appeared.

This also happened in the scenario when first I send files to Trash and then right click its icon and clicked the option "Empty Trash". The same dialog tried to appear but crashing the whole app.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
