As it looks neither MuPad (in MC15, 14), nor Maple (in MC 11, see Luc's answer) nor Primes new symbolic engine are able to give you the symbolic result which WA arrives at.

 

But you sure have found a bug in MuPad, as its symbolic and subsequently its numeric result 0.43239... is wrong.
Primes new symbolic, while in some respects even weaker than muPad, does not suffer from this bug.

BTW, the symbolic result given by MC11's Maple (see Luc's picture) is equivalent with the symbolic result of Primes new symbolic engine, given that

and Primes new symbolic on the other hand is not able to do this simple simplification
