Comment 46 for bug 882956

From ~/.xsession-errors:
----------------------------------------
(gnome-terminal:1915): Gdk-WARNING **: The program 'gnome-terminal' received an X Window System error.
This probably reflects a bug in the program.
The error was 'XI_BadDevice (invalid Device parameter)'.
  (Details: serial 10608 error_code 149 request_code 141 minor_code 48)
  (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 _only_ happens with 3.0.x (i.e. 2.6.40.x) kernels. Looks like other folks are seeing this too, in bug #720792.
