Comment # 5 on bug 1026960 from Fabian Vogt

We definitely need this as we need to update KDE Applications to 17.04.
KDE Applications 16.12 made its *last* bugfix release this week so we need to
use 17.04 to have something usable in 42.3. This also requires a bump of KDE
Frameworks, which needs the newer gpgme as well.
