The problem was that you tried to move a clip to a negative timecode. MLT does 
not support it and Kdenlive did not correctly detect the failure.

In case of negative timecode, you should do a 2 step command. For example, if 
you want to move a clip to -3 seconds:

1) Resize clip start to crop the first 3 seconds
2) Move the clip to 0
