I had this problem too with 3.0.8 and SBr 0.96. It took me 5 minutes
to view a ticket and seemed reproducible. The database was on a
different host and is running Postgres 7.2.1. 

I tried it out with a colleague's MySQL database -- he gave me r/o
access to his RT data -- and it flew.

Then I went back to my Postgres to chase up the bug, and the problem
mysteriously vanished.

Sorry this report isn't very useful.
