Backlog JIRAs NPE?

[Jeff Eastman]

Everything on that page is broken for me. The other releases seem to 
work. Is it repeatable?

Here's an example:
https://issues.apache.org/jira/secure/IssueNavigator.jspa?reset=true&jqlQuery=project+%3D+MAHOUT+AND+fixVersion+%3D+Backlog+AND+resolution+%3D+Unresolved+AND+priority+%3D+Major+ORDER+BY+key+DESC&mode=hide
