And?
I told you to try to revert marble, not digikam.

Again, to be clear, install marble-15.08.2 (and other related packages like
marble-data and marble-kde) from the standard repo and see if it fixes your
crash.

Actually I would recommend you to remove KDE:Applications completely and forget
about it.
You won't miss much anyway, as many applications cannot even be built for 42.2
any more in 16.12 because they require newer KDE Frameworks.

KDE:Extra is being built for standard 42.2 (not KDE:Applications), there may be
incompatibilities.
