What steps will reproduce the problem?
1. open http://rietest.appspot.com
2. sign out if already signed in.
3. open http://rietest.appspot.com/user/gae.test01

What is the expected output? What do you see instead?
Expected to see the list of issues for user gae.test01.
Got 500 server error instead.

Looks like you found a bug in r427 (which we haven't pushed out yet, luckily).

Let me know if this fix works: http://codereview.appspot.com/96168
