Unfortunately, the problem seems to have something to do with
pyOpenGL, as the problem (the type error cited above together
with a segmentation fault) occurs when calling
gtk.gtkgl.widget_get_gl_drawable in the sample script below.
The problem does not occur, when a widget delivers None as its
gl_drawable (e.g., if widget_set_gl_capability has not been
called).
thanks for any hints!
