Issue on Mandriva - KDE

[sandman772]

The program 'rolauncher' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadContext'.
  (Details: serial 17 error_code 155 request_code 144 minor_code 5)
  (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.)

This is what i get when I run regnum online. Anyone know anything about how to fix it??
