I am using a (sequence of) scripts to massage and tag some mp3 files
prior to adding them to rhythmbox.

In particular I am using eyeD3 to add tags, including comments.

But rhythmbox seems to behave very intermittently;
I created a blank mp3 file, added a comment to it:

eyeD3 --remove-all eg.mp3
eyeD3 -c "eng::harry" eg.mp3

I then dropped this into an empty rhythmbox;

This displays correctly with a "harry" comment, on exit the rhythmdb.xml
showed <comment>harry</comment>

So far, so good.

I then (in a restarted rhythmbox) edited the comment to be "harry2",
and confirmed (by re-opening the edit dialog) that this had "taken".

Exiting and checking, I found that rhythmdb.xml
showed <comment>harry2</comment>
and that running eyeD3 on the mp3 showed
Comment: [Description: Comment] [Lang: XXX]
harry2

All looking good.

But on re-starting rhythmbox, and opening the properties dialog
yet again, it shows NO COMMENT.

Worse, on exiting from this run of rhythmbox, the
rhythmdb.xml shows NO COMMENT.

And yet eyeD3 still shows
Comment: [Description: Comment] [Lang: XXX]
harry2

Since I am presently using the comment box to hold episode
synopses of radio programs (which is important to me), this is "unfortunate".
