Continuing.
The program 'gnome-settings-daemon' received an X Window System error.
This probably reflects a bug in the program.
The error was 'XI_BadClass (invalid Class parameter)'.
  (Details: serial 212 error_code 133 request_code 131 minor_code 6)
  (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.)
