as per subject, I previously logged in using OpenID/Google.  Now when I try, I get the error:
This OpenID https://www.google.com/accounts/xxxxxxxxxxxx is new to Jenkins. Would you like to sign up?

I can see that my account (matt.devillier) still exists, but have no way to mitigate the above error.  Even if I wanted to sign up, the CAPTCHA image isn't shown, so I'm unable to do so

thanks,
Matt
