There recently was a race condition fix related to mlt_property in MLT git. Does the crash still occur using latest MLT from git?
Do you use more than one thread for MLT?

Sorry, this morning it was working fine, and now its crashy again. :/

It's a bit random. It crashes mostly when there is a lot of effects / composite.
