GtkListStore memory leak?

[Todd Kulesza <todd dropline net>]

Hi,

	I know this is more of a gtk-app question, but if anyone knows the 
answer there, they're not responding.  I'm working with a rather large 
GtkListStore, and finding that calls to gtk_list_store_clear do not free 
any memory.  At first I thought this was because of caching issues, and 
that the memory would be used when i added more items to the list. 
However, my memory consumption only increases.  My program now uses 176 
megs of ram while running, but the data itself fits in a 300k xml file. 
 Is this the intended way for a list to work?  Is there something I 
have to do to free the memory manually?  I've looked at the source to 
GTK+ and found no calls inside gtk_list_store_remove_silently that seem 
to actually free the column data from each row, and I can't figure out 
how to use the row-deleted signal to free it, either.  Thanks,

Todd
