I'd call this a bug.  The change is an accident, a side-effect of the fact
that in 2.5.1 the coefficient (mantissa) of a Decimal was stored as a
tuple, and in 2.5.2 it's stored as a string (which greatly improves efficiency).
Clearly in 2.5.2 the mantissa is being stored as a unicode instance in the
second case;  it should be explicitly coerced to str in Decimal.__new__.

If others agree that it's a bug, I'll fix it.
