Hello,

It is because we have
libtasn1-3/libtasn1-3-dev/libtasn1-3-dbg/libtasn1-3-bin
libtasn1-6/libtasn1-6-dev/libtasn1-6-dbg/libtasn1-bin (where the
versioned -dev packages conflict) and the three abovementioned
packages have dependencies in the generated binary packages on
libtasn1-3-dev:

ametzler at argenau:~/TIN/TASN$ grep-dctrl -FDepends libtasn1-3- -sPackage /chroots/sid/var/lib/apt/lists/ftp.at.debian.org_debian_dists_sid_main_binary-i386_Packages
Package: libgcr-3-dev
Package: libgnutls-dev
Package: libimobiledevice-dev

Once libgnutls-dev moves to libtasn1-6 it stops being co-installable
with the other two mentioned packages.

The reason why we have versioned conflicting -dev packages is that I
needed to have both available in sid for an extended period of time. -
libtasn1-6 has minor API breakage and the respective changes to
gnutls26 were not eligible for wheezy freeze.

What I did not mention before is that shishi will also need a
sourceful upload, as it b-d on libtasn1-3-dev, but that can be done in
a second step, as the binary package is stil installable after
libgnutls-dev has switched to tasn1-6.

ametzler at argenau:~/TIN/TASN$ grep-dctrl -FBuild-Depends libtasn1-3- -sPackage /chroots/sid/var/lib/apt/lists/ftp.at.debian.org_debian_dists_sid_main_source_Sources
Package: gcr
Package: gnome-keyring
Package: gnutls26
Package: libimobiledevice
Package: shishi

I am ready for gnutls. The other two packages have outstanding
bug-reports
- libimobiledevice 2013-12-08 <http://bugs.debian.org/731707>
- gcr 2013-07-08 <http://bugs.debian.org/715354>
sadly both without maintainer feedback yet. All three packages are up
to date in testing.

If you want me to I can obviously make libtasn1-3-dev/libtasn1-3-bin
empty transitional packages built from libtasn1-6 which would limit
the actual transition to binNMUs.
