I figured it out eventually. First of all, the XML tree presented wasn't 
quite correct - apparently, "<Root> ... <popups>" shouldn't be included in 
this case. I tried with and without them, though, and the menu failed to 
be popped up in both cases. However, the menu failure turned out to be a 
result of the way I'd set up my widget tree. The applet contained a pixmap 
within a button - I don't remember why, but perhaps this was necessary in 
GNOME-1. Apparently, the button caused mouse clicks to be mapped the wrong 
way or something so that the popup would fail. I have now changed the 
layout so that the pixmap is added directly to the applet widget, and the 
menu shows up just fine now. The callbacks still don't do what I expected, 
though - I *really* need the debug support to be able to figure out what 
is going on.
