----------------------------------------+------------------------------
I restarted media services (from Media preflet) while having MediaPlayer
opened (dunno if it's related) and that crashed media_addon_server.
This was in VMware Fusion without any sound cards detected by Haiku, i.e.
OpenSound not installed.
