I can reproduce 100% of the time and crossfade doesn't help. Playback sometimes continues after a while (3-4 minutes in the most recent case I saw) and the song jumps to a position close to where it would have been if it had been playing from the beginning.
The following transitions cause a pause:
mp3->ogg
mp3->flac
ogg->flac
flac->ogg
These do not:
ogg->mp3
flac->mp3
I don't have other media types in the library to test with.
