Dashboard crash: Install of 1.3beta2 on linux with orion 1.5.4 and postgresql 7.2

Did a clean install of jira1.3beta2, went through the setup fine.

When I log in, I get the following error, and (sometimes) below that is the regular jira dashboard form with just the left hand side of the dashboard only (the Assigned to Me, Reported by Me areas are not there):

Per Mike's recommendation, I created an issue, assigned it to myself and then marked the issue In Progress. I logged out and then back in again and still got the above error when displaying the dashboard. And when I clicked on Browse Project, the Summary displays the correct numbers, including one In Progress Issue.

Then, if I click on any of the links to the IssueNavigator, I get the following error:

The following is displayed in the console window back on the server: ((I get the no descriptor found error whenever I click on a link to filter)

I can perform any of the Administrator functions, and if I know the key for an issue, I can go directly to that issue and view/edit/resolve/comment it.

Per Mike's suggestion, I changed to a hsql data source, went through the setup and then recieved the same error messages.
