devstack duplicate keypair problem

Hi Devstack team,

Just testing devstack on Ubuntu 12.04 server Virtualbox environment. That after creating keypair the dashboard becomes unresponsive momentarily. After reloading the page and creating the keypair for the second time, there appears a exact duplicate of the keypairs. I attempted to delete the keypair but I was greeted by this error instead:

ValueError at /project/access_and_security/
Multiple matches were returned for that id: [<Keypair: test1>, <Keypair: test1>].

Could the problem be related to reloading the dashboard? I haven't tried yet removing the keypair on the command line.
