[PyQt] QSettings error on Windows

[Scott Frankel]

Hi,

I've put together a simple test app that demonstrates the problem I'm  
having with QSettings.value() INT arguments on Windows.

An invalid argument type error causes the app to crash on startup.   
Line 37 of the attached file is the culprit.  The line works without  
issue on OSX.  Do I need to wrap the integer setting value in a string  
to work around the invalid type error?  What's common practice for  
wrestling with integer Windows preference settings?

Thanks!
Scott
