This appears to be because libtag1v5-vanilla has no non-comment lines in its
symbols file, resulting in generation of a dependency on libtag1v5-vanilla,
whereas the -dev depends on libtag1v5 (and dh_sameversiondep expects that
the symbols file/shlibs will generate a dependency on that too).
I attach a patch for taglib which lets taglib-extras compile. The
modified taglib appears to be functional in trivial testing with btag(1)
in an up to date sid chroot. I don't have any media files that require
taglib-extras, so I can't test that.
In principle all dependent packages should be binNMU'd afterwards (to pick up
the intended versioned dependency on libtag1v5 instead of an unversioned
dependency on libtag1v5-vanilla); but libtag1v5 currently depends on
libtag1v5-vanilla with no alternative anyway, and older versions of
libtag1v5 do not exist, so there's no real need to do the binNMUs.
After the dust has settled, I think the taglib maintainer should seriously
consider dropping the "flavour" arrangement and just building libtag1v5
as a conventional library package, but that doesn't seem like a decision
to be made in an NMU or during a 3K-package transition.

I'll NMU if nobody either objects or takes responsibility.
