Yes, but this certainly needs an API change.
int attrib[] = {
GDK_GL_DOUBLEBUFFER, FALSE,
GDK_GL_RED_SIZE, 8,
GDK_GL_GREEN_SIZE, 8,
GDK_GL_BLUE_SIZE, 8,
0
};
FALSE is equal to 0, so the binding code will abort there and never
reach the RGB sizes. The only solution is to pass the array length as an
extra parameter to the C function.
If you don't have a better idea, I think we should do this and deprecate
the zero-termination completely.

I won't have the resources for maintaining the code, but I wouldn't mind
putting the sources of some small, self-contained examples into my tree
(e.g., into examples/python/).
