Pi Sqrt[Pi]/(2 2 Sqrt[2])

The explanation for the "big bad bug" from Wolfram is that 
the Simplification rules for Power conflict.  The expression
is "simplified" back and forth between two different forms.
Will fix in another release, they say.  There is no really 
satisfactory fix.

Here is another big bad bug:

Integrate[E^( - k1*r[1]),{k1, 0, Infinity}]

Note that this expression correctly evaluates in version 2.0.
