XGL导致程序崩溃求助

按gentoo-wiki HOWTO XGL说明安装XGL后， leafpad、xfce4-panel 容易崩溃：

~ $  leafpad
The program 'leafpad' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 1173 error_code 16 request_code 154 minor_code 20)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

$xfce4-panel
The program 'xfce4-panel' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 540 error_code 1 request_code 149 minor_code 2)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
