Eli, this is why you see small (10x10 points) picture. Emacs/libungif
happily allocated small region of memory and then wrote the data
somewhere...

So, what should be done? The entry in etc/PROBLEMS is true and should be
there. There is no way to test for patched version of libungif when
compiling, because the real version used could be on different computer and
we should test it on run-time. The author of this version did mistake by
not incrementing minor version number so it is not possible.

The second problem (Geometry) can be solved by this patch:

   /* Create the X image and pixmap.  */
   if (!x_create_x_image_and_pixmap (f, width, height, 0, &ximg, &img->pixmap))


I use it for about two weeks right now and do not see problems (because
I use patched 4.1.0 libungif from SuSE). This patch should go to RC and
HEAD.

Without my patch:

pavel@SnowWhite:~> LD_LIBRARY_PATH=/tmp/ROOT-4.1.0b1/lib/ /tmp/emacs-21.1.90/src/emacs -q -f auto-image-file-mode ~/.Emacs/Work/x1.gif 
Fatal error (11).Neoprávněný přístup do paměti (SIGSEGV)

Wit my patch:

pavel@SnowWhite:~> LD_LIBRARY_PATH=/tmp/ROOT-4.1.0b1/lib/ emacs -q -f auto-image-file-mode ~/.Emacs/Work/x1.gif

it works. I will commit it in a moment.
