Julien has NMU'd gstreamer0.10 and scheduled some binNMUs, and swami has
migrated, so all we're waiting for to achieve this is for gstreamer0.10
to migrate. (This can be tracked by waiting for #697025, which is also RC,
to migrate.)

So, assuming no serious problems with the NMU, it's only a matter of time
before full upgrades are OK.

Regarding the original bug, gnome-dvb-daemon was recently built on the
affected architectures; it is now built on all Linux architectures.
So, from that point of view, job done.

As for partial upgrades: Julien's NMU of gstreamer0.10 bumped the shlibs,
so if dependent packages are rebuilt (up to 22 source NMUs of Multi-arch: same
packages, and up to 38 binNMUs of other packages,
see http://bugs.debian.org/694525#59), certain broken combinations
(namely: new dependent package, old gstreamer0.10) will be prevented.
There hasn't been any systematic upload of these; it's an open question
whether it's worthwhile to do all of these, or just the binNMUs, or neither.

The other broken combination (new gstreamer0.10, old dependent package)
can only be addressed via Breaks relations. I think Julien's conclusion
was that this has an unacceptable risk of introducing weird upgrade bugs
where apt fails to find a solution, similar to
<http://bugs.debian.org/676485>?
