Yes.

I've made some investigation and I found that the problem source is in 
gtkselection.c:

#ifdef GDK_WINDOWING_WIN32
/* No chunks on Win32 */
#define GTK_SELECTION_MAX_SIZE(display) G_MAXINT
#else
#define GTK_SELECTION_MAX_SIZE(display)                                 \
  MIN(262144,                                                           \
      XExtendedMaxRequestSize (GDK_DISPLAY_XDISPLAY (display)) == 0     \
       ? XMaxRequestSize (GDK_DISPLAY_XDISPLAY (display)) - 100         \
       : XExtendedMaxRequestSize (GDK_DISPLAY_XDISPLAY (display)) - 100)
#endif

I think it should be necessary to redefine GTK_SELECTION_MAX_SIZE when 
GDK_WINDOWING_DIRECTFB is defined, or else it uses X dependencies.
