OK. im now "contains" an image.

The image from im is now "pointed to" by gdkpm. im's image is now
NULL (you've *moved* it).

gdkpm2 is now NULL.

		  ^^^^^^ That's a NULL pointer.

I don't know what advice to give you on how to fix your code, because it's
difficult to figure out what you're trying to do :-)

Perhaps one of the assignments should use gdk_imlib_copy_image? However,
you'll then end up drawing one pixmap onto another, where the destination
already contained the image you were copying .... ?
