OK, let me think this through. We don't have to worry about the guy who always tells the truth, so we won't think about him. And we only have to worry about the guy who always lies if he is standing in front of the door that leads to death. So, there he is, standing in front of the door that leads to death, and if we ask him,

"Yo, my man, what would you tell me if I asked you whether that door leads to freedom,"

he would say, "I would tell you that it does lead to freedom." And you would go through it, and die.

Well, try it again. We ask him,

"Yo, my man, what would you tell me if I asked you whether that door leads to death?" And he would say,

Hmm, he might say, "I wouldn't tell you that it leads to death," or he might say, "I would tell you that it did not lead to death," and either way the double negative would give him away. Cool!

(Why does this make me think of Clinton?)

I see now that I didn't read the question clearly - it was a question about a question This opens a whole new can of worms. Either the liar or the honest fellow can now give a non-answer which technically stays within bounds.
"What would you say if I asked if this
was the door to freedom."
All he'd have to say is "The truth, my man, the truth", and you'd be out your one question and have zero information.
It seems vital to ask a direct, unambiguous question to avoid this way out of giving anny information - correct or otherwise. To me this remains one equation with two variables, and these have no single solution.
