Should be fixed for Kdenlive in latest svn revision (3737) - the parameters now have a maximum value depending of the project size (width and height). However, those values should probably be checked in the MLT filter so that we don't end with a crash when setting a too high value.

For example, the crash can be reproduced in melt:

melt myvideo.mpg -attach crop bottom=1500

Thanks for this fix!

Yes, this has also been a problem.
However, my initial error report was wrong in that I said you have to use SD DV.
This is not reproducible with SD DV. Sorry!

I initially meant to say take an MP4 or flv video...
I attached a very short flv video (remove the .txt) that still crashes SVN 3741.
Just drag onto the timeline, drag crop filter onto it and increase buttom value by a few pixels (sometimes it already crashes at 1, sometimes a little later).

Workaround: Deactivate Crop filter, adjust value, reactivate filter...

Btw: The movie's thumbnail in the bin is incorrect..
