Glade MenuBars cause errors

[Jeff Trefftzs <trefftzs tcsn net>]

I'm trying to use Gtk2::GladeXML and perl Gtk2 to build an app that
(among other things) contains a toolbox with a menubar.  I tore my hair
out over it all day yesterday and find the same problem recurs today:
If I include a menubar, even if I define all the callbacks, I get a
whole raft of errors as soon as I make the

        my $glade =  Gtk2::GladeXML->new("knitit.glade");

The errors look like this:

 ... repeat ad lib

The number of repetitions of the "accel_path" errors seems related to
the number of entries in the menu.  So far I've just been using the
default glade menu, with File, Edit, View, and Help top level entries; 
File, for example, contains New, Open, Save, Save As, a separator, and
Quit; and I've provided the appropriate callbacks for each of these.

The example program (fileman.glade) in the source works fine, with no
errors, and I can't see what I'm doing (or not doing) differently, but
my code just generates oodles of errors as above whenever I add the menu
bar.  I have also noticed that the number of error messages is directly
related to the amount of stuff in the menus (when I stripped it down to
contain only File/Quit, I got far fewer messages).  

The weird thing is that the resultant code seems to run, and the
standard menu accelerators are there, and work.  Alt-F/Q actually quits,
just as it should.  Yes, I do have callbacks for all the menu entries.

What am I missing?

Thanks,
