Comment 20 for bug 447431

I'm getting this or similiar error on Mint Nadia. On every login gtk theme "crashes" and .xsession-error contains:

(gnome-settings-daemon:1878): Gdk-ERROR **: The program 'gnome-settings-daemon' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 770 error_code 8 request_code 131 minor_code 22)
  (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.)
