Investigate why the Tor Browser AppArmor profile allows starting Totem

1. Copy a video that’s not supported by Tor Browser (e.g. .flv) to ~/Tor Browser/.
2. Open Tor Browser
3. In about:config, set browser.download.forbid_open_with to false.
4. Visit ~/Tor Browser/ and click the unsupported video.
5. Choose “Open with” -> “Videos (default)”
6. After a while Totem plays the video; in ps faux it’s not a child process of Firefox; Totem is running under its own (enforced) AppArmor profile.
