This seems to be same problem referenced here
(http://groups.google.com/group/google-appengine-python/browse_thread/thread/def
1b7b41a22803f/21fdf99a7db7b4a5#21fdf99a7db7b4a5),
however I have a admin with a valid email address and that does not solve
the problem.

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

Should have received a verification email

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

Please provide any additional information below.
