Also submitted this info on github - this one feels more like a bug:In osticket 1.9 RC1, downloaded 5/1/2014, we spotted what appears to be

an issue in include/client/header.inc.php . There is a section of code

that displays the text "Guest User" (lines 55 and 56) based on the

client registration mode being public. However, if the configuration is

such that clients must register (a new feature of 1.9), then

displaying "Guest User" makes no sense as their can never be an actual

guest user. The test $cfg->getClientRegistration() == 'public'

should likely be OR'd with a test for whatever variable corresponds to

the field Admin page => Settings => Access "Require registration

and login to create tickets".
