I love tux commander, it's probably the most useful 'advanced' file manager that I came across. Why? - Because it can copy and overwrite all older.
This is a feature I very much learned to appreciate and even more annoying that I currently can't use it.
Everytime I try, it will crash the moment it starts to copy. When I then start again, it will crash even earlier.
I started the debug mode and attach the debug information...
Hope this helps,
