EmpiricalDistribution bug

Here is a (bad) bug involving EmpriicalDistribution:

PDF[EmpiricalDistribution[{1}], 1]

produces error messages and returns

Boole[{1}[[GeometricFunctions`BinarySearch[{{1}, "Sorted"}, 1]]] ==
   1] {1}[[GeometricFunctions`BinarySearch[{{1}, "Sorted"}, 1]]]

Here is an (awkward) workaround:

PDF[EmpiricalDistribution[{1}], x] /. x -> 1

which returns 1.

I have submitted this to support at, but I'm hoping someone
lurking from wolfram will look into this and figure out a code patch
that can be applied right away. Thanks.
