BadWindow (invalid Window parameter)

$ tuxedo-control-center

(tuxedo-control-center:110473): Gdk-WARNING **: 16:24:24.582: The program 'tuxedo-control-center' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 755 error_code 3 request_code 2 (core protocol) minor_code 0)
(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.)
