Hi Albert, Jeremy,

libkipi and libkdcraw are not co-installable because icons are
installed in the same place as in their kdelibs4 versions

Here is how these libraries are used by KDE Applications:
    libkipi: gwenview, spectacle, ksnapshot (kdelibs4)
    libkface: <none>
    libkexiv2: okular, kdegraphics-thumbnailers (kdelibs4)
    libkdcraw: gwenview, kdegraphics-thumbnailers (kdelibs4)
    libksane: ksaneplugin (kdelibs4)

There is little left to do until we can drop libkipi/kdelibs4 and
libkdcraw/kdelibs4 from KDE Applications 15.12:
 - Move KSnapshot to extragear,
 - Have kdegraphics-thumbnailers ported to KF5 in KDE Applications 15.12.
