Facebook Connect Troubleshooting

It appears I have most of FB connect setup correctly - at least from the key/secret, FB verification, etc.  Test user hitting FB registration and I get this on response redirect return to the UNA site.
"CAN'T DEFINE YOUR PROFILE INFORMATION"

The obvious answer here is missing a field of data or a mismatch but I am doing the out of the box install.  Name, Email.  
Suggestions on where to troubleshoot next?
