Hi,
Thanks for report this bug who seems linked at MLT (and the video too) with this last version (0.7.0).
I don't see what we can do for resolve it but could you re-done the same operation using gdb (like it is explained here : http://openshotusers.com/forum/viewtopic.php?f=12&t=180). More we will have some informations, more we could resolve it.
