Summary: defint(exp(cos(x))*cos(sin(x)),x,0,2*%pi) wrong result 0

Initial Comment:
The correct result is 2*%pi. This is a new bug appearing in version 5.21.1. Previous
versions (<= 5.20.1 )  return just the integral expression unevaluated, which is fair enough, but 
most importantly is not a wrong result.

Maxima version: 5.21.1
Maxima build date: 8:13 4/26/2010
Host type: i686-pc-mingw32 also on linux system (fedora11)
Lisp implementation type: GNU Common Lisp (GCL) also with cmucl
Lisp implementation version: GCL 2.6.8 also with cmucl 19f
