Bug in MiniMaxApproximation

it seems to me that MiniMaxApproximation fails each time the given 
function is zero at the beginning of the specified interval
Consider an example from the Help:

MiniMaxApproximation[Exp[x],{x, {0, 2}, 2, 4}]

this works fine. However, if you change the function to 1-Exp[..]:

MiniMaxApproximation[1 - Exp[x], {x, {0, 2}, 2, 4}]

you get an 1/0 error.
