Application: dolphin (18.04.0)

Qt Version: 5.10.1
Frameworks Version: 5.45.0
Operating System: Linux 4.16.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

Cleaning up some files in the Downloads folder I selected a .pdf file (8,4 MiB in size) and pressed the delete key on my keyboard. Deleting was in progress for a few seconds after which Dolphin crashed. The removal itself however was successful (file was moved to the Trash bin).
The file in question was opened before without any problems and showed no signs of corruption. After restoring it from the Trash bin and deleting it again no crash happened. Therefore I couldn't reproduce the crash.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
