gio.File --- removing attributes

[Romano Giannetti <romano dea icai upcomillas es>]

Hi,

	First of all, sorry if I am writing to the wrong mailing list. I am
looking for a way to remove an attribute by using
gio.File.set_attribute() call. In the C equivalent, it seems that
passing a NULL value_p will remove the attribute. I tried various way to
do that, without luck. 

	To explain: I can set an emblem for a file like that: 

mydir=gio.File("./tmp")                                                   
mydirr.set_attribute("metadata::emblems",                                    
  gio.FILE_ATTRIBUTE_TYPE_STRINGV, ["RGeducation", "hot"]) 

but after that I did not find any way to pass the equivalent of NULL to
the value to completely remove the attribute. If I pass a [], the
attribute is still there, with a [] value. 

On the other end, by l-tracing gvfs-set-attribute -t unset ./tmp, it
seems that g_file_set_attribute is simple called with a NULL value_p. 

It's me doing something bad here? Thanks for any help.
