Unable to find child widgets of an hbox

[Al Dugas <adugas analog com>]

I am attempting to use the code below to find several child widgets of a window.  In this window is a vbox.  
Within the vbox are an hbox, table, and combo.  Within the hbox are two labels and two combos.  Within the 
table are a vbox, hbox, and drawingarea.  The code below is able to find all of the wigets listed except for 
the widgets contained within the hbox.  Does anyone know if this is a bug in gtk+1.2.8?  Any and all help 
would be appreciated.  Thanks in advance.
