Bug#885803: libgnomecanvasmm2.6: Don't release with Buster

[Jeremy Bicha]

Source: libgnomecanvasmm2.6
Version: 2.26.0-2
Severity: serious
User: pkg-gnome-maintainers at lists.alioth.debian.org
Usertags: oldlibs libgnomecanvas
Tags: sid buster

As announced [1], we do not intend to release Debian 10 "Buster" with
the old libgnome (and related) libraries. These libraries have been
deprecated and unmaintained for several years.

Please port your package to GTK3 and related maintained libraries.

We should be able to remove libgnomecanvasmm2.6 from Debian Testing
soon.
