I see this problem in Hardy. Note that I successfully added 'cpugraph' once, the problem may only have occurred after I removed it and attempted to re-add it. I have not (yet) found a work around. The following was logged into ~/.xsession-errors
The program 'xfce4-cpugraph-plugin' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAlloc (insufficient resources for operation)'. (Details: serial 187 error_code 11 request_code 53 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.) ** Message: CPU Graph: screen changed: 0 ** Message: No valid plug window.
