We show that the distribution P(g) of conductances g of a quasi–one-dimensional wire has nonanalytic behavior in the insulating region, leading to a discontinuous derivative in the distribution near g=1. We give analytic expressions for the full distribution and extract an approximate scaling behavior valid for different strengths of disorder close to g=1.
