Follow-up:

mask = gdk_pixmap_new(widget->window,childMapSize.X,childMapSize.Y,1);
                                
                                gdk_pixbuf_render_to_drawable_alpha(pixbuf,mask,
              0,0,0,0,childMapSize.X,childMapSize.Y,
              GDK_PIXBUF_ALPHA_BILEVEL,
              1,GDK_RGB_DITHER_NORMAL,0,0);

Gdk-WARNING **: The gdk_draw_*_image require the drawable argument to
have a specified colormap. All windows have a colormap,
however, pixmaps only have colormap by default if they
were created with a non-NULL window argument. Otherwise
a colormap must be set on them with gdk_drawable_set_colormap

... I created the pixmap with a non-NULL window argument (inside an 
expose handler). Yet...
