With the recently fixed bug of multiple title clips disappearing during expansion of a MLT/Kdenlive library clip I now see another bug that may be caused by this fix: when a library clip has the same bin clip (image clip, title clip) used multiple times in the timeline, then after expansion the bin will hold multiple instances of the same image or title clip. Could this be a producer identity issue during expansion? This is especially unfortunate in case a title clip needs to be edited, then all its clones need to be edited separately. I would expect that all clones of the same image and title clip are being fused into a single bin clip instance, instead of multiple clone clips. Reproducible: Always
This seems to be a serialization issue with MLT, which causes multiple instances of the same producer getting serialized.
