Public bug reported:
If one visits the user options page with a hand crafted query fragment or post data containing for example
the fact that the options CGI sees 'email' as a list rather than a string throws an exception in Utils.websafe().
We will defend against this by testing in Utils.websafe() for a sequence argument and if so, returning only websafe of the first element.
