Hi,
Effectively, it is strange. Directly, Openshot works yet with GTK2 and Python 2.7. At least this version, same if the work is already done in a branch.
At first look, it seems that the value for the slider is not found.
How have you installed Openshot (i.e Ubuntu Software Center, PPA (which one Official or developper )) ?
A advice , remove completely Openshot and re-done an installation using the Official PPA.
Good luck.
