I got no problem on Oneiric. The problem that we have is on Natty and he provides of a bug of yelp (who is not updated yet).
I don't know if it can help us but try to run Openshot in a console and open the help entry in the menu help and put us the result to see what happens.
The manual is in the version 1.3 because we have not yet put some news features in Openshot. Don't worry for that it will come with our big version. Be patient for that, it will come this year.
