impossible to open pitivi video editor Version: 0.10.1-1

Impossible to start Pitivi ; when i lauch it by the terminal, they say :

noil@lionux:~$ pitivi
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 36 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.)

As i'm stinky in computer science, i don't understand :/
I tried to uninstall it and install it again, but same thing happens.
