That's strange. Did you start from a fresh 16.04 or upgrade from an earlier LTS?

From the errors, it looks like it's having problems with libGTK. maybe it got corrupted? Try reinstalling that package.

I have a 16.04.1 LTS that was upgraded from 14.04 and VO runs fine.
I also made a fresh 16.04 VM and VO runs in that as well.
