MPD crashes: terminate called after throwing an instance of 'std::logic_error'

Bug report

Describe the bug

mpd crashes immediately on startup. does not even scan music folder. I built the program from source on Ubuntu 20. It installs, but starting up mpd just crashes. Installing directly from 'apt' (sudo apt install mpd) works fine. No errors. And the old mpd.conf just works. with version 0.22 that is installed from apt. So that's interesting.

Plot thickens: If I download the source file for the apt pkg, from https://packages.ubuntu.com/source/hirsute/mpd, mpd_0.22.6.orig.tar.xz, compilation works but mpd again fails to start. ??

Log

NO LOG GENERATED !!!

Need backtrace. See https://mpd.readthedocs.io/en/stable/user.html#crash

[c2b2pss]

Max, The error was 'I think' in due to files of unrecognized format. After removing these files using

mpd --no-daemon --stdout --verbose

and rebuilding from source, its is fixed. Although, mpd should not get stuck ever on files, you can close this issue for now. I am using a slightly different source which I will in my other open discussion.

Thanks again for the real timely repsonses!!!!

[c2b2pss]

Please close this issue for now.

[MaxKellermann]

No, please post a backtrace. This is a bug, and it's not fixed, even if you were successful making the crash go away for you.

[MaxKellermann]

Closing because @c2b2pss refuses to cooperate.
