Our users trying to use OAuth to provide us with their MySpaceID credentials are seeing '500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.' when redirected to http://api.myspace.com/authorize?oauth_token=.
The 500 error occurs even without passing any parameters, ie, just visiting http://api.myspace.com/authorize causes the error.
The calls to http://api.myspace.com/request_token are return request tokens just fine.
