So, test case:
- Remove the tiger plugin (set its rank to NONE), so katedec + textoverlay get
used.
- Get the Stephen Fry "GNU birthday" video
- Play it in Totem
- Select a subtitles language
- Select the second
- Wait a bit

When selecting a language while one is currently selected, the code will go
through the wrong-state return path. Waiting a bit will cause the pipeline to
stop (after queues dry out I think).
The Stephen Fry video is good at showing this as it's got subtitles all the
time, but it "should" happen with any video that's got at least two text
tracks.
