Exhuming this old thread with apparently no final answer.
I found that one of the issue in the initial code was the call to
modify_font.
I replaced it with a call to set_font_description on the layout.
This is the working code, that takes markup into account:
def get_pango_string_size(str, font_name=TEXT_FONT):
label = gtk.Label()
pango_layout = label.get_layout()
pango_layout.set_markup(str)
pango_font_desc = pango.FontDescription(font_name)
pango_layout.set_font_description(pango_font_desc)
return pango_layout.get_pixel_size()
Hope this helps.
Thanks

You should use the PangoLayout to retrieve the pixel size of the text. Use:
label.get_layout().get_pixel_size()
to get the width and height of the label string in pixels.
