Resolution Note:
The file is in an invalid state.
Without information on how it got into that state, and without a better idea of the prevalence of this issue (so far we only have one report), it would be premature to add costly consistency checking to the PlayableDirector loading routine.
If you get into this situation, it is probably due to multiple entries with the same key under the m_References section of the scene file where the PlayableDirector is saved.
The workaround in this specific case was to delete any references that looked like this (- : {fileID: 0}).
