In some cases, playback error in a plugin lock the player

In some cases, when you play a internet video from a content plugin, the content provider return a html error instead of a video stream.

Moovida displays an Gstreamer error box "no codec found for (...) Text/HTML content". After this, it's not possible to play a video anymore. The player stays in an inconsistent state.

An easy way to reproduce it is to use a hacked movie trailer plugin :
Go in elisa/plugins/apple_trailers/models.py and change line 72 by :
source_properties = {'user_agent': ''}

The following steps are valid in any case with this hack :

Step to reproduce:
1. Launch Moovida
2. Play a Trailer from your hacked plugin
3. A error pop-up message is displayed
4. Try to play any other video (local or streamed)

Expected result : it works

Current result : impossible to play a video anymore
