Ran into this with a temporary config which has the lyricswiki plugin enabled. Might be a known issue, since there's a "FIXME" comment in lyricwiki_playback_began() which seems related.

The strcmp() call in the get_lyrics_step_3() async method crashes easily with state.uri being a NULL ptr when lyricwiki_playback_began() unrefs it and resets it to NULL while the vfs async operation hasn't finished yet.

The smallest test-case is to add two unknown .ogg files to the playlist, then start playback and switch between the two tracks forth and back. Lyricswiki redirects to the 40KB edit page, and vfs async access takes more time than switching tracks.
