Currently crash at launch with GNUstep. It worked fine previously. I thought it was caused by changes in emacs, but someone has confirmed it works fine with the stable packages of GNUstep (I will test it tomorrow). So the problem could be in gnustep. Below I
add the backtrace. The app crash because can't retain a pixmap.

Here the backtrace:

(gdb) backtrace
#0  objc_msg_lookup (receiver=0x1400016, op=0x8482710)

#2 0x08255ac2 in XGetImage (display=0x89af8e8, pixmap=0x1400016, x=0, y=0, width=64, height=64, plane_mask=4294967295, format=2) at image.c:160

#4  0x089af8e8 in ?? ()
#5  0x01400016 in ?? ()
#6  0x00000000 in ?? ()

At frame 2 the function XGetImage is:

XGetImage (Display *display, Pixmap pixmap, int x, int y,
           unsigned int width, unsigned int height,
           unsigned long plane_mask, int format)
  /* TODO: not sure what this function is supposed to do.. */
  ns_retain_object (pixmap);
  return pixmap;

And at frame 1 the function ns_retain_object is:

ns_retain_object (void *obj)
/* --------------------------------------------------------------------------
    Retain an object (callable from C)
-------------------------------------------------------------------------- */
    [(id)obj retain];

Can this problem be related with the changes about how the images
are handled? Any idea? Thanks.
