TabHost, xoom & Honeycomb

My App dies on the xoom when I load a TabHost.

The Error is
sub:tablist_activity_create
android.content.res.Resorces$NotFoundException:Resource ID #0x0

It does the same thing in the TabHost Example, it dies at

Activity.LoadLayout("main")

Which is a designer loaded TabHost, the only item it the view.

Any Ideas?
