The player may emit a listener event when shutting down, and since websockets didn't remove it's listener callback it would receive an event despite being deinitialized. This would lead to an invalid read by lws_cancel_service in listener_cb().
OwnTone (previously forked-daapd)
OwnTone is a Linux/FreeBSD DAAP (iTunes), MPD (Music Player Daemon) and RSP (Roku) media server.
It supports AirPlay devices/speakers, Apple Remote (and compatibles), MPD clients, Chromecast, network streaming, internet radio, Spotify and LastFM.
It does not support streaming video by AirPlay nor Chromecast.
DAAP stands for Digital Audio Access Protocol which is the protocol used by iTunes and friends to share/stream media libraries over the network.
OwnTone was previously called forked-daapd, which again was a rewrite of mt-daapd (Firefly Media Server).
