I see yes. The original was ok I think, but it must have been a typo when
I switched the boolean to a enum on Thomas request and for some
reason the new breakage didn't show up on my testing.

I wonder why you didn't keep the enum even though Thomas
insisted on it. Since you removed it again the safest would have been
to just keep it correct as it originally was. And it was rather pointless
to force me to do changes when you then afterwards half way rewrite the code 
anyways. To be honest that habit makes it rather unpleasant to submit
patch to you recently. At least you could have indicated that in advance
and safe everybody trouble.
