7822	Creating a OneToOneField with a related model breaks the list_filter interface in the related model	ElliottM	nobody	"This has happened since before the NFA merge. The summary of the ticket pretty much says it all. 

If you create a model (let's call it ""UserProfile"") and give that model a OneToOneField to another model (In this case ""User""), the list_display interface will disappear on the User model's change list. If you change the o2o to a foreignkey, the list_filter panel comes back.

An entire project is included (admin_test.zip).

In this case I did User and UserProfile, but it appears to happen with any OneToOnefield."		closed	contrib.admin	dev		duplicate	admin onetoone o2o list_filter		Unreviewed	0	0	0	0	0	0
