I'm not sure these two issues are related. Before I look deeper, have you updated from SVN today? I fixed a bug earlier today related to using the STIX fonts (which appears to be where this is crashing) on narrow Unicode Python interpreters (which I believe Win32 Python is).
Occasionally I get these ob_refcnt assertions when distutils didn't decide to rebuild enough things. Try doing a clean rebuild (if you haven't already).
