gnome-glade-gtk-perl layout convergence issue

I've got a glade app (bins-edit-gui, next version) that isn't doing
what I think it should, and I'm looking for suggestions as to how to
deal with the problem...  I've experimented some but not gotten much
change.

The key part of the app (full widget hierarchy at the end of this
message) is a display of an image (digital photo) and a list of
attributes of the photo.

AspectFrame has a <ratio> of 1, ie. square.  The abstract goal is to
devote the largest possible area to the Pixmap, and then give the rest
to the Clist.  The pixmaps are, in practice, either 4:3 or 3:4, and
a typical screen (and thus a maximized window) is usually of a similar
ratio, so this scaling works out.  Having the square aspectFrame
leaves us with consistent image "size" ie. area, without having to
be too creative with varying image sizes.

However, it doesn't quite work: I end up with blank space at AA.  It
does apear that the label is centered in the vbox, rather than above
the frame, since image_filename_label is GTK_JUSTIFY_LEFT, I assume
that the child:padding/expand/fill settings of the vbox are causing
this.  This space doesn't show in glade, which just gives the twho
halves of the hbox equal space - actually putting something in the
gtkpixmap is what changes things, it looks like.

This may also tie in with something I mentioned earlier about getting
the interface to converge -- I want GTK to figure out how much
viewport I have, and then I'll put an image into it.  Instead, that
seems to trigger further resizing, unless I explicitly prevent loops
in the expose_event handler...

What I'm looking for, I think, is some suggestion that indicates what
mistake I've made in the window layout, or what assumption I'm
violating, or something like that -- something I can fix :-)
