DEBUG (0x57af60 - 0:00:01.044749000)               python(14220) viewer.py(210):_createSinkThreads: about to set_xwindow_id (73400404)

Gdk-ERROR **: The program 'pitivi' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 46 error_code 3 request_code 3 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.)
