Version 3.38.0 has been out for a bit, and includes a fix for bug #751700 Reproducible: Always I'll attach an ebuild that compiles+installs for me. It fails tests because they depend on connecting to an online resource (musicbrainz), which obviously work in the sandbox. I don't know the best way of fixing this, whether tests should simply be disabled, or left in but commented out, as it seems there is only the one test.

Sorry, should say the tests obviously don't work in a sandbox.
Done.
