Very bad, a segfault. Please install debug symbols and provide a stack trace.

Sure that this is a debug build or the debug symbols are installed?

Try running a debug build it with valgrind:

./build.sh debug
valgrind --leak-check=full --exit-on-first-error=yes debug/bin/mympd

This was very helpful. Fix is in devel, could you test?

I'm affected by the same issue since the upgrade from 12.1.1-1 to 13.0.0-1, unfortunately I didn't have a chance to report this earlier.

Just for reference my stack trace:

I just tested the devel branch at 178d2a9ad861 and the issue is resolved.

The fixed version will be released the weekend.
