GtkListStore memory leak?

[Todd Kulesza <todd dropline net>]

hi,

	i've been working with the new GtkListStore and am having trouble freeing 
memory with it.  if i clear a list with gtk_list_store_clear () and add 
more items to the list, my memory use increases.  if i clear the list 
and don't add any items, the memory use  doesn't drop.  i'm working with 
items which have ~80 fields, so after refreshing the list view a couple 
of times, my application goes from useing 11 megs of ram to 25.  is 
there a proper way to free the list memory, or is this a gtk+ bug?
