Subject: bug in integrate, is anyone working on this?

sin(x)^2/sqrt(1-cos(x)^2);
integrate(%,x,-1,1) returns 0, but the integrand is
always non-negative.
integrate(%,x) returns cos(x) which is not
right either.
Mathematica gives -cot(x)*sqrt(sin(x)^2) :)
This kind of integration problem is not new.
