Yep. The integrate(sqrt(x+1/x-2),x,0,1) is in the testsuite already.

Subject: Old Macsyma bugs still present
I dug up this discussion of some integration problems in Macsyma, and a
test of cvs maxima shows they are still there for us:
http://library.wolfram.com/mathgroup/archive/1990/Nov/msg00033.html
Key points:
"I only fixed MACSYMA a few months ago to get e.g.
integrate(sqrt(x+1/x-2),x,0,1); -> 4/3, instead of -4/3 ."
Significant, nontrivial integration problem:
(c1) /* The following gives the wrong answer: */
integrate(sqrt(2-2*cos(x)),x,0,2*%pi);
