------------------------- ERROR 2 ------------------------------
Failed to import 'from openshot.openshot import main'
Error Message: 'NoneType' object has no attribute 'set_cursor'
----------------------------------------------------------------

OpenShot has failed to import some of the Python files or libraries 
required for our application to run.  Here are some trouble shooting
tips:

Tip 1) Check if MLT can be successfully imported in Python.  Run the 
 following commands, and see if any errors are displayed.  If you get 
 an error, you need to investigate the correct way to install MLT.
 NOTE:  Do not type the $ or >> characters in the examples below.

       $ python
       >> import mlt
       >> mlt.Factory().init()

Tip 2) If MLT is working from the first example, then the next tip is 
 to look at the above error messages very closely, and google for more 
 help.  It's likely the problem is already reported, and maybe there is
 a simple work-around.  Also, you can search for bugs or report a new 
 bug at https://bugs.launchpad.net/openshot.  Good luck!
