user tags fetch returns tags no longer in use

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Tag a photo and then remove that tag from the photo
2. do a fetch for all tags of a user:
GET https://picasaweb.google.com/data/feed/api/user/userID?kind=tag

3. the tag that is no longer associated with any photo is still returned. The 
tag feed does not indicate the number of photos tagged with each so there is no 
way to filter based on no photos.

What is the expected output? What do you see instead?

If there is no reason to keep them around, don't return tags that have no 
photos associated in the main tags feed. If there is a reason tags need to 
remain, then at least indicate the number of photos for each tag so empty tags 
can be filtered out on the client end.


What version of the product are you using? On what operating system?

gdata v 2.0 on objective c (ipad iOS v6)
