I hope someone does, because I don't. But until someone comes up with the answer, here are possibly relevant questions: Did you build mpl from source? If so, did you delete the build directory before rebuilding with 2.5? My guess is that there is a version mismatch somewhere, and this is the sort of thing that can occur if a major change is made and a complete rebuild is not done. setup.py is not smart enough to always know what really needs to be rebuilt, I think.
