Fix for rather inaccurately titled bug [ 1165306 ] Property access with decorator makes interpreter crash Don't allow the creation of unbound methods with NULL im_class, because attempting to call such crashes. Backport candidate.

/* Minimal main program -- everything is loaded from the library */

#include "Python.h"

extern "C"
DL_EXPORT(int) Py_Main( int argc, char *argv[] );

int main( int argc, char *argv[] )
{
	return Py_Main(argc, argv);
}
