should be fixed in later kde3 version (many crash positions where cleaned)

since the main work is now put into kde4-port, there is not so much time to
fix the kde3 version also. kde4 version is in many part new written and
should have not so much of this issues.

this was working for me in the kde3 version

yes this is a good point, i'll add this to the kde4 porting page, so that it
can be solved in the kde4 version

must be tested (can you fill a bug report for this ?)

also no idea how this looks

nice, user response is very important to help improving kdenlive.
