Attempting to link second google account results in 500 error (BB-8475)

I already have my work google account linked with bitbucket, tried to link my personal account too when logging in and got an ugly 500 and this code: c2c54c187d0c4567a73b5a32ca51ecff

1. As a logged out user attempt to sign in with google
2. Attempt to log in with unregistered google account
3. choose to link account with existing bitbucket account (with one google account already linked)
4. Receive error
