This is a DLL/SO load problem. It's an exception thrown by the 'init_gtkgl'
function in file gtkglmodule.c where it tries to register all the Python
visible classes from GtkGLExt. If an error occurs due to not being able
import all the dependent modules, then this fatal exception is thrown.

Check the following,

- Python DLL/SO version matches with PyGtk and PyGtkGLExt requirements
- PATH contains location of the correct binaries of Gtk-2.2.x and
GtkGLExt-1.0.x
- PYTHON_PATH contains location of the correct libraries of PyGtk and
libGlade.

Hope it helps. Cheers.

Alif.
