Compiled code does not work properly with Nuitka

Hello,

I am the author of Nuitka, a Python compiler with very high levels of compatibility. In the past I managed to contribute patches for wxpython and PyQt that made them work with Nuitka as well. A typical issue is that PyMethod_Check and PyFunction_Check won't say true on compiled functions. Yet they should be used.

I am attaching an example, that when compiled won't ever call the callback when the signal is sent, if compiled. Nuitka needs no installation really, I accept that you may not want to install it. http://nuitka.net

I have attempted to look at Shiboken and PySide itself, but it seems I fail to find the exact spot, where to change code. Can you lend me a hand and point me. I see there is a registry of types and conversions and ways to attach stuff. Compiled methods e.g. have im_self and other attributes that can be used to achieve the effect.

Thanks in advance,
Kay
