Since this commit it crashes when a video is removed : java.lang.NullPointerException: Attempt to invoke virtual method 'void org.videolan.medialibrary.interfaces.media.MediaWrapper.removeThumbnail()' on a null object reference at org.videolan.vlc.viewmodels.CallBackDelegate.deleteThumbnail(CallBackDelegate.kt:133).

That's probably because in OnMediaDeleted, the media is already deleted, so medialibrary.getMedia will return null.

Could you please open an issue?
