Unable to fetch photos that have tag names containing dash (-) characters

What steps will reproduce the problem?
1. On Picasaweb I tagged using text that contained a "-" in it.  Specifically I 
tagged a photo with "water-drive" in Picasaweb.
2. In my code I instantiated gdata.photos.service.PhotosService() (let's call 
the created object gd_client)
2. Call gd_client.GetTaggedPhotos(user="intakescreensinc", tag="water-drive")

What is the expected output? What do you see instead?
0 results returned, expect at least 1 result.

What version of the product are you using?
2.0.13

Please provide any additional information below.

I tried this same behavior using tag names that didn't have a "-" character in 
them; replacing the tag with an underscore "_" character seemed to work just 
fine.  I can't find anything in the documentation that says that dashes aren't 
allowed.

Any help would be greatly appreciated, thanks!
