[otrs] column q.first_response_time does not exist

Tue May 15 17:24:37 GMT 2007

I installed a 2.2.0 beta 2 debian package

I can't select personnal queues.

When I try, the answer is a success message : "Preferences updates 
successfully!", but the selected queue stays unselected.
By "System log", I read error message OTRS-CGI-10:
Found no $ID for 46!
Error: column q.first_response_time does not exist

The system is Debian Etch 4.0, Postgresql 8.1

Steps for install

1 - 2.0.4 debian package standard
2 - imports of previous data
3 - 2.1.7 debian package, without upgrading database during intallation
4 - upgrade database by script to 2.1.7
5 - 2.0.0 beta 2 debian package, without upgrading database during 
intallation
6 - upgrade database by script to 2.0.0

There were no error messages during upgrades of database.

Is there an error, or is there a patch ?
