Application: dolphin (17.12.2)

Qt Version: 5.10.0
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Was transferring files between external hard drives. Empty folder was ready to delete. Pressed Shift + Del to delete the folder, skipping the recycle bin. The program crashed. I tried to delete with just Del, crash. Tried right-click -> Delete, crash again. I tried to create folder on local drive so I could test deleting there. Same behavior.

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".
