interwiki and InterWiki have different keys. nothing weird there.
The name test+people is highly strange. I can't reproduce the issue with any other combination. I think it has something to do with the fact that person and people have the same key (it knows about that pluralization). Until we find some more instances, I don't think we can act on this.
OK, I can't say that I fully understand this, but i tried this again and was getting server errors. there was a busted old card on the test dwagn with a tmp key called "name test+people". I deleted that and everything seems to be working fine now.
Not completely satisfying, but I don't think there's much left to do here...
