I didn't want to step in. The last time we have upgraded numpy warning about division by zero have appeared in doctests in that file: doctest:1: RuntimeWarning: divide by zero encountered in divide Working on the numpy 1.7.0 upgrade (not yet released) more of these warnings have appeared. Every time we have the following line in a test: sage: m = Riemann_Map([f], [fprime], 0) It doesn't correlate to any of the error you reported but it adds to the feeling that something needs fixing in that file.
