I hope you can read the version/log/config file?
It is included in the post (e.g. when I edit it) but not shown for some reason?

[MaxKellermann]

You made your paste invisible by leaving the comment syntax in.

Your backtrace is useless because your MPD executable is stripped. I need a backtrace with debug info.

[Utini2000]

@MaxKellermann yes sorry. I re-ran with "verbose" logging. I hope this is correct?

The log is too big to paste here and will crash any paste-services. I uploaded it to my webserver:

Hey, why are you reporting bugs for an outdated version?
