[Pkg-mpd-maintainers] Bug#768094: mpd: crashes with std::logic_error on database update

[Matteo Cypriani]

Package: mpd
Version: 0.19.1-1
Severity: important

Dear Maintainer,

Since yesterday's update from 0.18.16-1, mpd crashes in the middle of updating
the database. It can still play the music that already is in the database. Here
is what I get in /var/log/mpd/mpd.log:

[…]
Nov 04 14:20 : update: added foo/bar.flac
terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_S_construct null not valid

It seems to crash after a certain amount of time (or files, or data processed),
not on a specific file. That being said, if I don't change anything in my music
directory, it always crashes on the same file. If I remove this file, it will
crash on something else.

Downgrading to 0.18.16-1 fixes the problem.

Please let me know if I can help further investigating this problem.

Cheers,
  Matteo
