Include disabled users broken?

I am using RT 3.4.0rc3 on Fedora Core 3. In configuration, the list of
users displays correctly but the checkbox for including disabled users
does not work. I can find those users by using the search fields, so I
know they are there. We need this to find users who have been added
automatically when sending email from home.

The feature works fine for us on the Queses. Groups is completely
broken. Once a group is disabled we can not bring it up even when
using the name in the search fields.

Is This a bug or am I doing something wrong?

Thanks,
