manager.authenticate causes exception when redirect URL contains a Hash ("#") history token?

What steps will reproduce the problem?
1. Set-up OpenID authentication with Google as the provider:
"https://www.google.com/accounts/o8/id"

using code like this:
     // obtain a AuthRequest message to be sent to the OpenID provider
     AuthRequest authReq = manager.authenticate(discovered, returnToUrl);

2. have "returnToUrl" contain an applications History token using the # 
character in the url. An example Url is:

http://127.0.0.1:8888/landing.html#Module-Inspections-

where the string after the # is an application specific History token.

3. The call to manager.authenticate causes the following exception (running on 
GAE locally):

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

Please provide any additional information below.

If you provide a url with query parameters like this:

http://127.0.0.1:8888/landing.html?test=true

then it all works fine...
