Audacious

Failure to start with the message * buffer overflow detected *,
Only change from last working state was adding song(s) to playlist(s) before poweroff,
so I tried cleaning .config/audacious/playlists/ and it worked.
rookie mistake : didn't backup the playlist files :(

- the following deps libcue,libfluidsynth,libsidplayfp,libwavpack
were missing on my system at the time (Arch distribution).
- the stack trace provided is the last before succesful start,
after the missing libs mentioned were installed.
