Same problem here.
Added Google account in 12.04 even though it was mostly unused. On upgrade I got these annoying and unlabelled (!) requests for a password... I couldn't even determine which account it was for because it only displayed an email address.
The solution here seems to do the trick https://bugs.launchpad.net/ubuntu/+source/gcr/+bug/1044549/comments/14
