Plasma requires - dataengine-microblog

An annoying pop-up has been irritating me since an earlier update. The purpose of this is neither self explanatory, nor seemingly to any purpose. The pop-up has the following text, ""Plasma requires an additional service foir this operation. The following service is required. Dataengine-microblog. Do you want to search for this now" there are options for "yes" and "no" Apart from a delay before a failed search, on opting for "yes", the net effect seems to be zero with either option Has anyone any idea how to kill this wreched pop-up, or satisfy it's demands. Or give a reason why this thing should be there?
