Here again, but note the error with the break command. I also was not sure whether to use "y" or "n" to its question, so I used "n".

[New Thread 0x7fffef1a6700 (LWP 7376)] [New Thread 0x7fffee9a5700 (LWP 7377)] The program 'gtk-window-decorator' received an X Window System error. This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 15597 error_code 3 request_code 20 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 --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.)
