Hi Samuel,
It does seem to be related, and I see we are still using taglib 0.3.1.
I will update it to the latest from the git repo, and install it, and let
you know if it fixes the problem.
There might be one little snag though, because apparently you need OCaml 4
to build the new taglib and we are still running on 3.12.1.
