Application: krusader (2.7.1 "Peace of Mind")

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.14.83-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
* Mount a remote NAS storage over NFS
* Synchronize directories: source is a directory on the local disk, target is a directory on the NFS mount. The synchronisation UI suggests that there are about 3G of data to be copied to the NAS storage
* Start synchronisation. After some time Krusader woudl crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Krusader (krusader), signal: Floating point exception
