Since the AudioSource v2 API was merged, Mixxx crashes when trying to analyze an empty (0 byte) .flac file with bulk analysis. This is reproducible every time. A backtrace and the end of the log are attached (see top of file for logging output).

Loading the track to a deck correctly pops up an error dialog without crashing.

The file came from ripping an audio CD with K3b, but apparently that didn't work for one of the tracks.
