[kdenlive] Problem with new keyframe import

[Harald Albrecht]

Hi Jean-Baptiste,

just saw your new commit for the keyframe import and gave it a try: yay! 
I could now successfully import the motion information into an affine 
transition, starting only from the offset where the clip region is 
placed on the timeline. Sweet!

Would it be possible to pass the crop start begin of the clip in the 
timeline to the import dialog in case both a transition and a clip has 
been selected?

I noticed something strange in the project bin: sometimes viewing the 
clip properties doesn't work. The pane then doesn't show up at all, 
albeit the project bin makes some room for it. But no clip properties 
tabs, nothing, nada. Restarting Kdenlive got it back. I now remember 
noticing this strange behavior already a few times in the past, but as 
it isn't reproducible (yet) I never reported it.

Alas, thank you very much for the improved keyframe import.

Best regards,
Harald
