Same problem after upgrade to 13.10 but none of the proposed solutions work.
Deleting the gstreamer cache only gives me an extra error about setting GST_PLUGIN_SCANNER This is the output I usually get from totem (don't worry about the theme warnings): :~$ totem (totem:28893): Gtk-WARNING **: Unknown key gtk-decoration-layout in /usr/share/themes/elementary/gtk-3.0/settings.ini (totem:28893): Gtk-WARNING **: Unknown key decoration-layout in /usr/share/themes/elementary/gtk-3.0/settings.ini (totem:28893): Gtk-WARNING **: Unknown key gtk-decoration-layout in /usr/share/themes/elementary/gtk-3.0/settings.ini (totem:28893): Gtk-WARNING **: Unknown key decoration-layout in /usr/share/themes/elementary/gtk-3.0/settings.ini ** (totem:28893): CRITICAL **: bacon_video_widget_has_previous_track: assertion 'BACON_IS_VIDEO_WIDGET (bvw)' failed ** (totem:28893): CRITICAL **: bacon_video_widget_has_next_track: assertion 'BACON_IS_VIDEO_WIDGET (bvw)' failed ** (totem:28893): WARNING **: Element 'playbin' is missing, verify your installation ** (totem:28893): WARNING **: Element 'audioconvert' is missing, verify your installation ** (totem:28893): WARNING **: Element 'scaletempo' is missing, verify your installation ** (totem:28893): WARNING **: Element 'autoaudiosink' is missing, verify your installation (totem:28893): Gtk-WARNING **: A floating object was finalized.

All of those plugins are installed for gstreamer0.10 AND gstreamer1.0. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1103747 Title: Totem could not startup.
