ANN matplotlib-0.53

I just uninstalled the 0.53b release and installed 0.53

This is a bug (clearly!). I didn't catch it in my tests because it
only arises when you get an OSError on a win32 registry call, which I
never got. I believe Paul lifted this section of the code from
ttfquery. For a quick fix, in the win32InstalledFonts function, try
replacing

        try:
            local = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, fontdir)
        except OSError:
            pass

with

        try:
            local = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, fontdir)
        except OSError:
            continue

and let me know how things go.

Paul, is the continue the correct behavior here?

Thanks for the report,

Yes. I'll fix it.

Hi John and Paul,
I changed the 'pass' to a 'continue' and a different problem has revealed
itself. Now, in lieu of any plot window, I get a Windows dialog with title
'Windows Visual C++ Runtime Library'

and content

Runtime Error
Program C:\APPS\PYTHON23\PYTHONW.EXE
abnormal program termination

Clicking the OK then generates a page fault. This seems a bit nasty. When I
have time later today, I'll see what happens under Win2000 on my laptop. I
should probably try another backend too.
