I'm running ubuntu 14.10 Utopic Unicorn with gnome-staging ppa activated (1). This means that I've the version 3.12.1-0ubuntu1~utopic1.
To reproduce the bug :
- Try to launch the application from the start menu

What happened : no window appear
What is expected : totem window should appear.

When I'm trying to launch totem in a terminal I get the following messages :
