Dear Maintainer,
I don't know if this is a bug in debhelepr or in vdr-dev
Feel free to reassign if needed.

It is a bug in `dh_vdrplugin_depends` / vdr-dev.
The package name is "vdr-abi-2.6.0-debian" without a newline in it. If
you were to add a version to this dependency then we would have ended
with the invalid substitution contents:
"""
vdr:Depends=vdr-abi-2.6.0-debian
(>= 2.6.0)
"""
which would have caused a parse error at dpkg-gencontrol time. Without
a version, you *often* get away without issues (but there are still
cases where this could go wrong)
In the concrete case, a version is unlikely to be added (as it is
embedded in the package name), but the newline could still cause grief
in other cases. Therefore, debhelper is now taking a "strict" approach
to substvars.
Thanks,
~Niels
