Bug 379353

Application: dolphin (17.04.0)

Qt Version: 5.8.0
Frameworks Version: 5.33.0
Operating System: Linux 4.10.11-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I tried to delete some items by pressing shift and del. But the same happens when I try to delete the contents in the trash. The dialog appears shortly and than dolphin crashs. I think, when I want to delete something, there would also be a dialog and that is the reason why dolphin crashs.

The crash can be reproduced every time.

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