Hola me da un error al abrir el programa Pitivi en Ubuntu Feisty Fawn2 el problema es el siguiente:


pillo@jump:~$ pitivi
/usr/lib/python2.4/site-packages/cairo/__init__.py:1: RuntimeWarning: Python C API version mismatch for module cairo._cairo: This Python has API version 1013, module cairo._cairo has version 1012.
  from _cairo import *
/usr/lib/python2.4/site-packages/gst-0.10/gst/__init__.py:108: RuntimeWarning: Python C API version mismatch for module _gst: This Python has API version 1013, module _gst has version 1012.
  from _gst import *
/usr/lib/python2.4/site-packages/gst-0.10/gst/__init__.py:109: RuntimeWarning: Python C API version mismatch for module interfaces: This Python has API version 1013, module interfaces has version 1012.
  import interfaces
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 38 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.)
