I've made what you want, but I've only tested in windows, but for what I've search it should work with nautilus too. The example its made with a gtk.Window but works perfectly for a treeview (its working on my project so far)
<code>
import gtk
import urllib
import os

# Drag and drop attributes
TARGET_TYPE_URI_LIST = 80
dnd_list = [ ( 'text/uri-list', 0, TARGET_TYPE_URI_LIST ) ]

def get_file_path_from_dnd_dropped_uri(uri):
        # get the path to file
        path = ""
        if uri.startswith('file:///'): # windows
                path = uri[8:] # 8 is len('file:///')
        elif uri.startswith('file://'): # nautilus, rox
                path = uri[7:] # 7 is len('file://')
        elif uri.startswith('file:'): # xffm
                path = uri[5:] # 5 is len('file:')

        path = urllib.url2pathname(uri) # escape special chars
        path = path.strip('\r\n\x00') # remove \r\n and NULL

        return path

def on_drag_data_received(widget, context, x, y, selection, target_type, timestamp):
        if target_type == TARGET_TYPE_URI_LIST:
                uri = selection.data.strip('\r\n\x00')
                uri_splitted = uri.split() # we may have more than one file dropped
                for uri in uri_splitted:
                    print(uri)              # Prints each file (but with file:///)

w = gtk.Window()
w.connect('drag_data_received', on_drag_data_received)
w.drag_dest_set( gtk.DEST_DEFAULT_MOTION |
                  gtk.DEST_DEFAULT_HIGHLIGHT | gtk.DEST_DEFAULT_DROP,
                  dnd_list, gtk.gdk.ACTION_COPY)
w.show_all()
gtk.main()

</code>

(I'm sorry, you'll have to fix the indentation)
What i'm still not sure about is get_file_path_from_dnd_dropped_uri, because i've test the program on gnome and vista and both returns file:///{uri}, but according to this function (I didn't made it) the string should be different, but its not. So give it a try.
Best regars, Joaquín.
