[GtkGLExt] X crash in double mode

[Alex Queiroz <ventonegro gmail com>]

Hallo,

       I'm basically using the logo.cc demo as a guide, but my
application fails when I request a double-buffered mode. The error
message from Gdk is:

=== BEGIN ===
The program 'orbis' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadColor (invalid Colormap parameter)'.
  (Details: serial 360 error_code 12 request_code 1 minor_code 0)
  (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.)
=== END ===

     If a request a single-buffered mode the application starts ok.
Has anybody seen this before?
