Installiert: 1.2-1

Hi,
a [replaygain --show file] by files without id3-Tag reports the Error, that is
no ID3-Tag is present:
replaygain --show test.mp3
test.mp3
<Error reading Replay Gain: ID3NoHeaderError(u"'test.mp3' doesn't start with
an ID3 tag",)>
By trying to write a replay gain value, the full python stack trace is shown:
$ replaygain -f --no-album test.mp3
Calculating Replay Gain information ...
test.mp3: -3.85 dB
Writing Replay Gain information to files ...
test.mp3:

ID3NoHeaderError: 'test.mp3' doesn't start with an ID3 tag
I think, it there be good, if in such a case python-rgain writes the id3-Tag
before storing the replay gain value, or give a defined error.
This bug is also reported here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=798137
It may be an alternative to take mp3gain in the repos until this bug is
fixed?
It affects ubuntu 14.4/16.4
Version of rgain in 14.4 is replaygain 1.2
