[otrs] CustomerUsers not visible after upgrading

Hi people, I just did an experimental upgrade from otrs 1.2.x to 1.3.2 and now the customers aren't assigned to the tickets anymore. I did add some extra fields but even when disabling these I still can't see the list of customers in the customeruser panel. When I create a new ticket I can search for a customer and it will find it, but when leaving te field blank the dropdown list doesn't appear. Any hints on where to look?
