There is a app named Minitube in ubutnu software center. It say's that it doesn't require any flash so i wanted to watch videos by it. After installing this app i tried to open it graphically but it was not starting. So i open up terminal and type "minitube" to open it but it gaved me following error:
minitube: symbol lookup error: minitube: undefined symbol: _ZNK7QLocale11uiLanguagesEv
Here is the result of apt-cache policy minitube
