Hi!
This package uses a native source format, with a non-native version,
which is rather confusing and subverts the semantics of both the
source and version formats.
This currently produces a lintian error, and with dpkg-dev 1.20.1 it
started producing warnings, but my intention is to eventually make
it error out, given the above, and because this is a common source of
this kind of accidental packaging bug.
Please, either use a non-native source format, or a native version,
so that these are coherent.
From the historical data in snapshot.debian.org, this would appear as
the build was done with a missing orig so dpkg-source considered it a
native format? I'd recommend switching to source format «3.0 (quilt)»
where this kind of accident cannot happen.
Thanks,
Guillem
