new BigInteger("0", 10) is not equal to BigInteger.nbv(0)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. trace("0==0: "+BigInteger.nbv(0).equals(new BigInteger("0", 10))); // false
2. trace("0==0: "+BigInteger.ZERO.equals(new BigInteger("0", 10))); // false
3. trace("0==0: "+BigInteger.ZERO.equals(BigInteger.nbv(0))); // true

What is the expected output? What do you see instead?
The first two should be true.

What version of the product are you using? On what operating system?
as3crypto v1.3

Please provide any additional information below.
1. new BigInteger("0", 10)
a: [0]
   length: 1
s: 0
t: 1

2. BigInteger.nbv(0) and BigInteger.ZERO
a: []
   length: 0
s: 0
t: 0

BigInteger.equals does a comparison of the value t which is not the same 
depending on the method of construction.
