Geoff, your getting to be like Chris.  Why not hose
both tribes and then take either path.

Anyway, the correct question is:

To any one of the two tribesman:
  Which path would the other tribesman say is the safest path?

Then take whatever path the tribesman DID NOT say was the safest.
Why?  If the tribesman you ask is the one who lies, then he will 
give the the opposite of the other tribesman answer (the  answer being
the correct path).
      If the tribesman you ask tells the truth, then he will give 
you the wrong answer, because he is giving the liar's answer which is
wrong.

That will be 100 gold , please.  Pay the dragon at the door as you leave.
