Application: dolphin (19.08.2)
 (Compiled from sources)
Qt Version: 5.12.5
Frameworks Version: 5.63.0
Operating System: Linux 4.19.75-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

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

Trying to copy a directory structure via fuse.sshfs resulted in a crash of dolphin. On second try immediately afterwards it worked fine, but this is not the first time it has happened.

The crash can be reproduced sometimes.

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