Maybe not just miniature black holes. I'm trying to work out what would happen to the light emitted towards the front of the Alcubierre bubble from the inside, and there's a possibility it'd get stuck there for the entire duration of FTL flight. Those are mere doodles as far as GR maths goes, but maybe you could end up with a kugelblitz in front of your ship after—or during!—a long enough flight.
