Description Milan Bartovic 2020-03-05 18:22:36 UTC

Application: krusader (2.7.2 "Peace of Mind")

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-40-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
There were two directories each with approx. 160 000 of smaller files (30kB). One directory had approx. 1 000 more.
I wanted to sync them.
No checkbox was checked.
Krusader has crashed in 30 seconds after the "Compare" was clicked.

The crash can be reproduced every time.

-- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
