>Description:
        Some programs (observed here in qemu (crashes when exiting input grab) 
and openoffice3 (hanging when clicking anything)) refuse to work, giving the 
following message:

        [xcb] Extra reply data still left in queue
        [xcb] This is most likely caused by a broken X extension library
        [xcb] Aborting, sorry about that.
        assertion "!xcb_xlib_extra_reply_data_left" failed: file 
"/home/builds/ab/netbsd-6-1-1-RELEASE/xsrc/external/mit/libX11/dist/src/xcb_io.c",
 line 575, function "_XReply"
                
        This started happening since I sysupgraded form 6.1 to 6.1.1.
