Bug Description

When you run python-dbg with the debug packages, if you call set_select_function on a treeview, whenever the function is called python-dbg will assert with the following error:

Fatal Python error: gtktreeview.override:671 object at 0xb83fb0 has negative ref count -1

Attached is a test program that reproduces this each time you select the item in the treeview.

Kubuntu 12.04.1
Python 2.7.3
PyGTK 2.24.0-3

Looking at PyEval_CallFunction, it appears that it expects the arguments to be referenced before they are passed in, as it dereferences them upon returning. By removing the Py_DECREF(pypath) at line 671 of gtktreeview.override, this bug no longer occurs.
