dr14 finds not all tracks in directory

[maplee0]

Hello!
Often dr14 adds to log not all tracks in the folder.
Use it: ./dr14_tmeter.py "dir path".
For some reason, last track in the folder is being recognized, but it's not in the result log.
There are 15 FLAC tracks in the folder, the log contains the first 14 besides 15th.
Not too often the same happens when penultimate track is not being added to log.
Tried to create a new dir that contains only that "missing" track.
Sometimes it helps, sometimes doesn't until flac file is re-encoded.
Prints "No audio files found".
Weird bug.
