#190 Freuquent crash "python: double free or corruption" when changing mlt.Playlist via Python bindings

[Janne Liljeblad]

Hello,

I have a frequent crash when doing edits with Flowblade (of which I'm the author of) that seems to be an MLT bug.

Crash happens when a mlt.Producer is removed from mlt.Playlist, but not very often, maybe 1-in-200 or something. I also believe that it is required that the removed mlt.Producer was displayed at the time of removal, but this is not certain information.

Backtrace attached.
