Well, I tested your example on Maemo and Ubuntu, and indeed the drag &
drop only worked on Ubuntu. Additionally, this error is shown on
console:

/tmp/dndtest.py:77: Warning: g_object_set_data_full: assertion
`G_IS_OBJECT (object)' failed
  gtk.main()

So I went further and translated your example to C (please note I'm no
GTK expert, I'm only trying to help debugging the problem). And the
same behavior is presented: the drag does not work and this message is
shown on console:

dndtest[9349]: GLIB CRITICAL ** GLib-GObject - g_object_set_data_full:
assertion `G_IS_OBJECT (object)' failed

That means the problem is not related to Python or PyGTK at all, but
some GTK limitation/bug on Maemo 5.

The translated C example is attached.

Any ideas anyone? Regards,
