(To put it another way, if this is > going to delay the release, then we need to revert that patch.) I think I'd agree on it being a release blocker. Given that your fix is really a one-liner (3 of the lines are just changing the variable name, which I agree with), I'd be fine with applying it on top rather than reverting the original, even if it means delaying the release slightly. It seems like about the same amount of risk to me. (Sometimes it's actually _less_ risky to apply the one-liner fix, because reverting a large feature can have unintended interactions with other features that were built in the meantime. Looking at the original patch, though, I doubt that is the case here, hence my "about the same amount of risk"). -Peff
