[otrs] Error on QueueView with new upgrade

Hi All , Ok so we decided to build a secondary OTRS system , sort of as a reference archive to our production system. I basically did a clean install of 2.1.6 on FC5 , copied over the 2.0.4 database and article data , followed the instructions of the UPGRADE.txt document to upgrade the database. All went fine , could log in but as soon as I click on a queue to view the tickets I get an error message : Can't use an undefined value as a HASH reference at /opt/otrs//Kernel/System/Ticket/Article.pm line 1363. I searched the otrs archives but to no avail , I think the ticket data in the database can't find the actual article reference? Also I did run the Setpermissions.sh script as well.. Any help will be appreciated. Daniel
