This message looks interesting.  It suggests that combining non-Computer 
Modern fonts with ams* packages can be troublesome.  Perhaps this has 
been fixed in recent LaTeX distributions, which is why it works for me.

I wonder if removing the

\usepackage{times}

from sphinx.sty fixes things for you.  Then we have the Computer Modern 
fonts, of course...
