[Santiago Vila]

Package: src:beets
Version: 1.3.19-2.1
Severity: important

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
but it failed:

This is just how the build ends, not necessarily the relevant part.

I've put several build logs here:

https://people.debian.org/~sanvila/build-logs/beets/

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

The bug should be reproducible with sbuild on a single CPU virtual machine,
provided you try enough times (as the failure happens randomly).

Thanks.
