Try Increase transparency bounces.

It takes a while to investigate this report because you need to run the smoke simulation.
However, as @mike (mikeblend) said, increasing max bounces for transparency seems to solve the problem.
So I think this is working as it should.
@Brecht Van Lommel (brecht), what do you think?
