[pygtk] set_use_markup and gtk.SpinButton

[Art Hunkins]

I am trying to use a variant of your first suggestion:
spin.get_layout().set_font_description('normal 10')

('normal 10' is even one of the examples in the reference manual). All I 
want to do is to set the size larger.

However, I get this error message:
TypeError: desc should be a PangoFontDescription or None.

"None" works, but I haven't been able to get anything else to do so, 
including ('Sans 10 Bold').

Any ideas?
