I think the following sequence was a problem:
* The app requests an add-on for a given file, and loads it
* The file is deleted, the media_server notices this and removes it from the 
decoder list
* The app tries to use the plugin, which asks the media_server for some data 
about itself
* The media_server already forgot about this add-on, which leave it in a 
non-working state.

Now, the plugins are more standalone and stay contained in application side, 
avoiding this problem.

sounds possible, but we need each app to manage this by itself (similar to
