Comment 1 caulier.gilles 2015-10-07 04:07:06 UTC

This is due to marble binary compatibility issue on your computer. The digiKam KIOSlave are broken and crashes. 

Updating libmarblewidget on your system must fix the problem.

In all case, next digiKam 5.0.0 will be definitely better in this situation, as all digiKam KIOSLAves are dropped in favor of pure multithreaded solution to query the database.
