OK, thanks for the confirmation and as promised I created:

     https://anonscm.debian.org/git/debian-science/packages/skimage.git

Please note: I removed debian/gbp.conf and used the branches as
described in Debian Science policy.  If those Uploaders who finally work
on the package prefer a different layout please document this in
debian/README.source.

I also commited a patch that's simply skiping the tests mentioned in
#840589.  I do not really like this kind of "hiding eyes from problems"
workaround and thus I would not really close bug #840589 but IMHO it is
apropriate to lower its severity and work on later on this together with
upstream (those who intend to keep on maintaining the package please
open an upstream issue - will not continue here).

Ole, if you would please commit the patch you named in #848112 and
upload the package to make sure it can migrate right in time and will
enable other packages to migrate as well?

HOWEVER, we have another problem:  If I build the current state in Git
I'm running into:


======================================================================

I'm opening a bug against python-numpy to revert the transition that
has happened after the transition freeze (see #848758 for details).

Kind regards

     Andreas.
