Binary package hint: kdesvn

lintian warns that several of the kdesvn binary packages symlink their
changelogs to libqtsvn5:

W: kdesvn: debian-changelog-file-is-a-symlink
W: kdesvn-kio-plugins: debian-changelog-file-is-a-symlink

This isn't a problem if the packages have a strict versioned dependency
that guarantees the changelog will be the same, but these packages only
depend on libsvnqt5 (>=3D 1.2.3) - which can easily lead to skew between
the package versions in the event of a partial upgrade.

These packages should have a hard-coded dependency on the matching
version of libsvnqt5, in addition to the shlibs dependency.

This symlinking is automatically done by cdbs/debhelper (can't remember
which of them now); wouldn't the right place to fix it be in those
packages, so they automatically changed it to a strict depends when
symlinking or only symlinked upon strict depends?

This really ought to be fixed by cdbs so it only symlinks in the right
cases.

Indeed, not caused by the kdesvn package.

This corner case with partial upgrades is known, it affects every source
package which builds multiple binaries. Few, if any, of them have such
strict dependencies for good reason.

If we only did the symlinking on strict dependencies, we couldn't
symlink pretty much any package, which would nullify the space savings
which we get with it. Thus this will not be fixed, I'm afraid.
