Tried to edit my previous post but seems there's no edit function in this forum.

Although there will be a clutch on the take up spool, John is correct in that it's the sprockets that control the film advance and they will be geared. It could be the rewind release is releasing itself if it's gummed up and not engaging properly in the first place (check to see if the release button pops fully out) or it could be the film becoming disengaged from the sprocket and the most likely cause of that is the clutch slipping causing the film to become loose on the take up spool.

Best way to find out is use a test film and run it through with the back open. It might take a few goes for it to happen but it's the only way to be sure.
