Sorry, I should had been a little more specific. As Michael pointed
out, the problem is gnome_parse_geometry. It properly scans the "-"
computes the proper values (with respect to the size of screen) but
the return values have no indication that they refer to the upper or
lower bound of monitor. I ripped gnome_parse_geometry from gnome-libs
and created a variation:

ggv_parse_geometry (const gchar *geometry, 
                    gint *xpos, gint *ypos, 
		    gboolean *xneg, gboolean *yneg,
                    gint *width, 
                    gint *height)

xneg and yneg are true if the coordinates are "negative".

Is anybody else interested in this behaviour?

Also, how do I compute the size of the titlebar as created by the
windows manager so I can properly located the window when the vertical
location is relative to the lower edge of the screen?

I don't know too much about X so I have no idea what exactly the
gravity is, can somebody point me to the proper location for more
information? I _like_ this behaviour in general, and I am willing to
hack to have it across GNOME applications (I believe it is feature
that it is too important not to have). I just need a little bit of
direction on what to do.
