/usr/bin/melt was already correctly set. Tried the script way and it renders same way as from GUI: no error messages, black video track.
I've checked that this problem occurs with any coded profile I've tried (H.264/AAC high, DV PAL 4:3, WebM, AVI XVid4). I've observed that "generate script" action saves an .mlt file, and this XML file contains a <playlist id="black_track"> clause. Is this only related to fade_to_black?
