Comment 14 for bug 1243354

I use "Separate X screen" configuration (I have two separate screen).
If you run the terminal on one of the screens, and then start on the other, the terminal on the first screen is closed. On one screen can run multiple copies of the terminal, but if you open it on another screen, as they are all closed.

---------------
The program 'xfce4-terminal' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 488 error_code 8 request_code 1 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.)
