Application: dolphin (17.08.0)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.12.8-2-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Attempting to delete any file. File types and special characters in file name did not seem to change this behavior. This particular instance of the crash happened while attempting to empty the trash can.

- Unusual behavior I noticed:

The files that I attempted to delete are not deleted. The confirmation dialog window appears before the crash, but does not have any buttons or text, but does have a title.

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".
