Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.4-1-ARCH x86_64

-- Information about the crash:
I selected a file in Dolphin and hit shift+delete. It briefly shows something where I'm supposed to confirm I want to delete the file before it crashes.

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".
