Change line 176 in id3.py from

    if self.title == 'genre':

to

    if self.title == 'genre' and len(val):

It's crashing when val is empty.

This will handle only if genre is empty.. what about if it is having string instead of integer?

I am having many mp3 files, where genre is with some other strings.
