[otrs] Installed, but can't create a user (RESEND)

Hi, I previously put a ticket in, but it seems to have stalled... (http://bugs.otrs.org/show_bug.cgi?id=2411) On a fairly fresh install, I can't add a user. Instead of bringing me to what I think should be the user input screen here : http://otrs.org/images/screen-2.0/user.png It gives me : Message: Need UserID! Traceback (1944): Module: Kernel::Output::HTML::PreferencesCustomQueue::Param (v1.7) Line: 49 Module: Kernel::Modules::AdminUser::_Edit (v1.42 ) Line: 383 Module: Kernel::Modules::AdminUser::Run (v1.42 ) Line: 214 Module: Kernel::System::Web::InterfaceAgent::Run (v1.23) Line: 670 Module: /opt/otrs/bin//otrs/index.pl (v1.81) Line: 47 The ticket has more info and some debug output... Thanks, Tuc
