There is defined some messages in no subspace and some in nb subspace, while Translatewiki.net uses nb. In addition both a nb and a no language is defined in the selector at no.wp. This creates a situation where some messages are localized and some are not.
For example will the header of this page fail.
This works

This fails
http://no.wikipedia.org/w/index.php?title=Mal%3ACitation&diff=10708724&oldid=9277851&uselang=nb
Actual failing message is MediaWiki:Difference-title/nb, it is defined in Translatewiki but not locally.
Only one language should be defined in the selector or both should be fully defined as complementary.
