Bug 410571

Application: dolphin (18.12.3)

Qt Version: 5.9.7
Frameworks Version: 5.55.0
Operating System: Linux 4.12.14-lp151.28.10-default x86_64
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed:
I was copying a few music folders (albums, mp3 and flac mostly) from a folder on an external drive to another external drive when Dolph suddenly ran screaming out the back door, leaving me all alone in my misery. This has happened a few times now, and I don't really see any reason why...

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
