Hey,
I don't know about this particular error, though can say Wikibase is no longer compatible with MediaWiki 1.23. Unfortunately retaining compatibility with a stable MediaWiki version, and third party support in general, does not appear to be high on the priority list of the Wikidata team. So I can only recommend against third parities using the software in serious contexts for now.
Yes we do require master of MediaWiki at the moment. My plan was to change this with MediaWiki 1.23. This didn't work out for various reasons. We will make an effort for 1.24. Wikibase is still changing a lot and people who want to use it for other purposes should be aware of that.
