[python-win32] pb with string conversion to float and GetObject call

[popov]

Ok, thanks for the test.
I can explain the difference in behaviour: I think you have '.' as the
decimal symbol for numbers in your regional settings. I have ','. Indeed, if
I change it to '.', it works. But I think it's not a solution: I would like
to keep ',' as the decimal point AND have the code working.

I think an explanation of the behaviour is that in the chain call initiated
by the GetObject call from python, some code modify the local settings used
by the current thread to make it use the settings set at the computer level,
and not the settings that the python interpreter may have defined itself...
So, when the call get back to python, the local settings now say that the
decimal point is ',' on my computer, which make the conversion from '8.4' to
float fail.
