Description of problem:
Pitivi doesn't start with the default options, when starting pitivi in the
terminal one gets the following error message:

"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 15 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.)
"

Adding the --sync flag makes pitivi run. By extension this means them menu entry
of pitivi doesn't actually launch the application. 

Version-Release number of selected component (if applicable):
0.10.1-5

How reproducible:
Every time

Steps to Reproduce:
1. yum install pitivi
2. open terminal, launch pitivi
3. Add --sync flag to make pitivi run
  
Actual results:
Doesn't run, runs with --sync flag

Expected results:
Should run with default options. Menu entry should launch application
