[ruby-gnome2-devel-en] FYI - assertion 'gtk_accel_group_from_accel_closure (accel_closure) != NULL' failed

[<Ra...@la...>]

I just ran across this assertion failure and wanted to document it 
somewhere in case someone else runs across it.

I have a Glade file containing a window organized with a layout containing 
a vbox.  The vbox contains two radio buttons with clicked signals defined. 
 For some reason the cell/column containing the vbox was wider than the 
others so I found that by specifying a width request of 1 on the vbox the 
widths seemed to look ok.

The problem was that as soon as I made this change I now get this 
assertion failure whenever I send :show to a Gtk::Builder object:

Gtk-CRITICAL **:IA__gtk_accel_label_set_accel_closure: assertion 
'gtk_accel_group_from_accel_closure (accel_closure) != NULL' failed

This appears to be related to the radio buttons in the vbox since I'm 
actually getting the assertion warning twice.

It was an easy fix for me because I knew exactly what I changed to produce 
the warnings - I just removed the width request on the containing vbox.

Hopefully this helps someone else who sees the assertion and wants a hint 
on where it might be coming from.
