moving menu in panel crashes panel

[Jeremy C. Reed]

Running xfce4-panel-4.4.2. I have glib2-2.16.3nb3 and gtk2+-2.12.10 (from 
pkgsrc) on NetBSD 4.0.

My panel has the "xfce4-menu".

I right-clicked this item and clicked on the arrow for move. A object 
appeared and I dragged it to the left side of my panel and left-clicked 
(hoping to move it there).

The panel and all of my X closed.

I repeated this a few times.

Core dump is below:

p.s. I got rid of my bottom small panel as taught in earlier mail so I now 
have more screen space. I added new items to top panel to replace it.
