Since we no longer provide a KDE 4 workspace, pretty much any package that
build-depends on workspace-dev is partly or fully non-functional. We ought
to, in short order, get rid of it. Here's the affected packages:
reverse-depends -b kdebase-workspace-dev
reverse-depends -b kde-workspace-dev
I did an upload today that took care of ktorrent. The rest of the packages
will either need an rm bug, update to a Plasma 5 version if one exists, or
some kind of packaging adjustment to build without workspace-dev to provide
the subset of functionality that works with Plasma 5.
Kubuntu has already gotten rid of the package, so in many cases there will be
hints in what they've done to follow.
