"Totem could not display the help contents"

The AppArmor profile for GNOME Videos aka Totem doesn’t allow executing /usr/bin/yelp, which causes the following error message when trying to open the help in Totem:

Totem could not display the help contents
Failed to execute child process "yelp" (Permission denied)

I tested this on 3.8 and 3.9~rc1 and both are affected.
