Returning NULL is the right thing todo IMHO, otherwise as apps read &
update the XML new attributes/elements will unneccessarily get added
to the doc.
Good point but doesn't this also apply to all enum props as well?
Currently all enum getters return a default value. Maybe we should
have a _NONE value added to all those enums and return that when no
value is set? Don't know what to do with uint* though except returning
0 or one of the G_MAXUINT* depending on the getter in question? Having
said that, we don't have any getters from uint* yet AFAICT.
