I say smoke him without a warning.
If he is stupid enough to do this, the gene pool needs some chlorine.
We had a similar, but considerably less severe, problem this last weekend. Our party Cleric was just being obstinate and non-cooperative for an extended period of time (over silly stuff like which way to travel in a silver mine).
To me, that's crap.
So at one point when I needed her light source to ensure the safety of the party and she refused, my psion took a step back and gooed her (i.e. Entangling Ectoplasm). She got all bent out of shape over it and ran away stating that my PC was possessed, but party Cleric or not, PCs have to cooperate. If they want to pull this nonsense about being argumentative for no reason, or stealing from the party, or other harmful as opposed to helpful activities, then they should be taken down a peg.
Your case is more severe than this and deserves an extremely severe response, but it doesn't matter your alignment. Theft is theft. All alignments should be against it (especially if done to you) and you smack down a thief in the party, just like you would smack down one from outside the party. Period.
