Incorrect exception thrown

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set the user credentials to be null or empty for the username and pass 
in a password on the service.
2. Try and insert a new album
3. Object reference exception thrown

What is the expected output? What do you see instead?
I would expect to see an invalid credentials exception.  Instead I get 
this:
System.NullReferenceException was caught
  Message="Object reference not set to an instance of an object."
  Source="Google.GData.Client"
  StackTrace:

newEntry)
       at Google.GData.Client.Service.Insert(Uri feedUri, AtomEntry 
newEntry)

What version of the product are you using? On what operating system?
The latest version, Vista Ultimate 64.

Please provide any additional information below.
I'm not absolutely positive of what produced the invalid exception, but 
this is what I had discovered.  I should have checked for those things 
first, but was surprised when I got the object reference exception.

project.  Delete this at your leisure.
