it's great that this fixes the pango problems. However --

-- IMHO the g_strdup shouldn't be used here, because g_locale_to_utf8 
returns a "gchar*" which IMHO means that this is an already newly 
allocated string. Unfortunately the documentation of g_locale_to_utf8 
doesn't clearly say this, but since it isn't a "const gchar*" I could 
only guess that the returned string is already newly allocated. So the 
g_strdup line should simply be removed.
