I'm experiencing the same issue, using fluidsynths sequencer API. It seems that this happens when the NoteOn event is inserted before the progChange evt, but still at the same tick as the NoteOn event. Thus a voice for the NoteOn is created and just afterwards the channels program gets set. This really sounds like a bug. But didnt have a detailed look at it, so I might be mistaken...
