-- 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
