Public bug reported:

Hello,
I'm on Fedora with:

openshot-1.4.3-3.fc23.noarch
ffmpeg-2.8.6-1.fc23.x86_64

Not sure if that was a trigger, but I have attempted to cut tail of last
clip after I have played it (maybe it was still playing) and that red
line which shows position was after last clip.

clip.py:1163:RenderClip:AttributeError: 'NoneType' object has no
attribute 'get_width'
