@Steven - thanks, that makes sense... unfortunately no matter how many times the accounts are removed and re-added (and the stored credentials in seahorse deleted), this does not resolve the problem here. Have created a blank user account on the machine and reproduced the problem.
A different google account works - the account name is in the format "<email address hidden>".
The account that does not work is connected to a non-gmail address, in the format "<email address hidden>".
Wouldn't be surprised if that's where the problem lies...
