Description of problem:

I receive the exact same error when trying to run gtkpod and gnome-control-center from the commandline.  I don't know if the problem is with the programs or with GDK.  I'm running them from within KDE.

]$ gnome-control-center 

(gnome-control-center:12685): Gdk-ERROR **: The program 'gnome-control-center' 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 440 error_code 1 request_code 156 (GLX) minor_code 19)
  (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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap
