g_type_query in gtk-win32

["John Emmas" <johne53 tiscali co uk>]

I'm trying to port a program which previously used gtk-x11 so that it will
work with gtk-win32.  For the past day or two I've had a very strange
problem with the program crashing unexpectedly.  Finally I tracked it down
to a problem with the function call  g_type_query()

Here's a very simple program that illustrates the problem:-

#include <libgnomecanvas/gnome-canvas.h>

int main (int argc, char *argv[])
{
   GTypeQuery base_query = { 0, 0, 0, 0, };
   g_type_query(gnome_canvas_get_type(), &base_query);

   return 0
}

'base_query' is initialised to NULL.  When I call  'g_type_query(...)'
(linked to gtk-x11) the various fields of 'base_query' get filled with
approriate data.  However, if I build the same program when linked to
gtk-win32, the call to  'g_type_query()'  simply fails to do anything,
leaving 'base_query' uninitiaised.

Please could someone try the above code and let me know if this is a general
problem - or whether there's something peculiar with my installation?

Many thanks,

John
