Application: kdiff3 (1.8.2 (64 bit))

Qt Version: 5.14.2
Frameworks Version: 5.71.0
Operating System: Linux 4.15.0-106-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.19

-- Information about the crash:
- What I was doing when the application crashed:
Compare a local folder and a folder using ssh (fish:// KIO worker). I tried using binary and date-size comparison for local (fish://localhost...) and remote folders.

- Unusual behavior I noticed:
Kdiff3 crash after showing the Directory Comparison Status which says that all files are different (that's not the case). The same folder can be accessed by dolphin without problems using fish://.

The crash can be reproduced every time.

-- Backtrace:
Application: KDiff3 (kdiff3), signal: Segmentation fault
