Pointer.set_pointer(None) causes Segmentation fault. #481

Isn't this supposed to be set to 0 (NULL)?

Code:

from memory import alloc

pointer = alloc(4, False)
pointer.set_pointer(None)

Output:

Thread 1 "srcds_linux" received signal SIGSEGV, Segmentation fault.
0xf0441c67 in CPointer::SetPtr(boost::python::api::object, int) ()

My first guess would be that pPtr is NULL there:
