DND in Seamonkey; GTK again?

[Joe Altman]

In January, this was widely reported:

https://bugzilla.mozilla.org/show_bug.cgi?id=367203
https://bugzilla.mozilla.org/show_bug.cgi?id=355248

In a nutshell:

Drag and drop of messages to folders broken in trunk around 2006/10/01

and 

gtk2 dnd implementation broken

A sample error: (Gecko:7527): Gtk-CRITICAL **: gtk_drag_get_data:
assertion `GTK_IS_WIDGET (widget)' failed

It was fixed, sometime around 18 Jan 2007 21:37:11; but I've just seen
it again in Seamonkey 1.1 Gecko/20070212; and this is the error on my
console:

(Gecko:916): Gtk-CRITICAL **: gtk_drag_get_data: assertion
`GTK_IS_WIDGET (widget)' failed

I also note that there are more reports at the two bug sites above.

My questions:

1) Is anyone else seeing this?

2) If anyone has seen it, did you notice a resolution following a
   ports update?

3) Has anyone seen a fix put into the relevant source?[a]

[a] I have no idea which source is relevant, actually; but it looks
    like the same GTK bits.
