Please describe the problem:
When I add a usenet account and groups, and then try to add them to a vfolder (that only matches on unread messages in it's constituent real folders) they add just fine but I don't actually see any messages from the group in the vfolder view.

Steps to reproduce:
1. configure a usenet server and subscribe to a group
2. create a vfolder that matches only unread messages (this step may be superfluous)
3. add the usenet group
4. view the vfolder


Actual results:
I don't see the usenet messages.

Expected results:
I should see the usenet messages.

Does this happen every time?
Yes
