Comment 19 for bug 805894

I can confirm the exact same behavior witnessed by Mike in comment #5 and Erwin above. In my case I have been trying to troubleshoot the extreme lack of theming in Oneiric - it never occurred to me to unplug my external WD My Book, which has been "recognized" as a keyboard for as long as I can remember but has never given me any difficulty.

Once unplugged, I can start gnome-settings-daemon fine, and windows are themed.

(gnome-settings-daemon:4587): Gdk-WARNING **: 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 873 error_code 8 request_code 143 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 --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.)
