I saw this yesterday on my system. The user has an invalid Solid predicate installed on their system. Check the directory $KDEDIR/share/apps/solid/actions/ which will contain a number of files. If it contains K3b ones, please ensure your k3b installation is up to date, they were broken yesterday and I fixed them. This is an outstanding bug I filed yesterday in Solid, which affects all Solid Action ( Predicates ) using applications. Ben Cooksley Solid Actions KCM Maintainer.
