Why does this small program cause an X11 BadMatch?

[Rich Burridge <Rich Burridge Sun COM>]

Hi all,

I've isolated the problem I'm seeing in converting an XView app to Gtk,
into the small example attached below.

Can somebody clue my in why this is giving me:

Gdk-ERROR **: BadMatch (invalid parameter attributes)
  serial 36 error_code 8 request_code 62 minor_code 0

It's the:

    gdk_window_copy_area(xid, svgc, 0, 0, xid, 0, 0, width, height);
    
that's bitching. 

Note that I need this GdkPixmap to be a depth of 1 as I want to use it 
later as a stencil in a GdkGC. It also needs to be created dynamically as
it might be a different width/height.

Thanks.
