Before anyone else wastes any time pondering this one, I should let you
know I already discovered what I was doing wrong.
My problem was not in the code at all, it was in the glade project file.
I was looking at the xml when I realised that I had another window
defined in the project (initially hidden) that had a pixmap widget with
the same name. When creating these windows from code there is no name
clash because the two pixmap widgets have different parent windows, but
it hadn't occurred to me that because of the manner of getting libglade
references via a string representing the individual widget name only
(eg. widgets.get_widget('widget-name')), the glade project file becomes
in effect a single "widget namespace".
The solution I guess (not that I expect anyone else to be silly enough
to make this mistake) is to either adopt a naming convention for your
glade widgets that differntiates between child widgets that perform the
same function on different parent windows , (which is what I did to
solve my problem), or to always define different parent windows
belonging to the same program in different glade projects.
Ciao,
Stephen.

More power to those who don't care for it.
