This is working with the gif-io at least.
Thanks a lot.

for my purposes the interface is sufficient. When i dont want looping,
i check whether i am on the last frame.

BTW here is the loader code:

static GList *get_anim_list( char *name ) {

   GError *err;
   GTimeVal time;
   GdkPixbufAnimation *animation = gdk_pixbuf_animation_new_from_file(
name, &err );
   GdkPixbufAnimationIter *iter;
   GList *retval = NULL;

   g_get_current_time( &time );
   iter = gdk_pixbuf_animation_get_iter( animation, &time );

   while(1) {
       GdkPixbuf *pixbuf = gdk_pixbuf_animation_iter_get_pixbuf(iter);
       int delay = gdk_pixbuf_animation_iter_get_delay_time( iter );

       retval = g_list_append( retval, gdk_pixbuf_copy( pixbuf ) );

       if( gdk_pixbuf_animation_iter_on_currently_loading_frame( iter )
)
           return retval;

       g_time_val_add( &time, delay*1000 );
       gdk_pixbuf_animation_iter_advance( iter, &time );
   }

   // not reached....
   return retval;
}
