Application: krusader (2.4.0-beta3 "Single Step")
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
This is reproducible:
1)In crusader start two FTP sesions to two different FTP servers in left and right tab
2)MOVE big file between these servers
3)MOVE operation goes to 100% but progress window hangs after that
4)Press cancel button, to close window with progress info
5)Watch Krusader "falling into pieces" ;)

- Custom settings of the application:
A lot. I made it look behave like MidnightCommander. F2-F10 key shortcuts as in MC. Colour schema as in MC. Krusader is installed on Ubuntu 15.04

The crash can be reproduced every time.

-- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
