Likely because KDE:Extra still doesn't build against KDE:Applications, only
against the standard distribution.

Maybe we should add a KDE:Applications target to KDE:Extra as I proposed on the
opensuse-kde mailinglist back then.
What do the other team members think?

Other than that, this is an upstream problem (in marble) I think.
It should rather not crash if the versions don't match exactly.
