Feed API does not return mediaGroup block for media:thumbnail elements

[GoogleCodeExporter]

What steps will reproduce the problem?
1. consume an rss feed (with the Google Feeds API) with images in
media:thumbnail tags, but not in media:content tags.  All Flickr feeds
return their media content in this way.  
2.
3.

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

I expect to get a mediaGroup block whenever the feed reader encounters any
media tags. 

Instead: if I consume a feed with images in media:content tags, I get a
mediaGroup block returned.  When I try to consume a feed with images in
media:thumbnail tags, I don't get a mediaGroup block.  

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

version 1.0 of the feed api.  It's a rest service, so I am just running a
GET against Google servers.  

Please provide any additional information below.

Updates from my testing: if you include media:group tags and other media tags
(besides thumbnail, like content, title, etc.), then the thumbnail tags are 
included.
 If media:thumbnail is the only media tag in a group, then there is no array element
for the thumbnail.
