Nepomukcontroller is a small systray applet that allows you to suspend and resume the Nepomuk file indexer. The systray was removed from KDE 4.6 to be ported to a stand-alone app which was not finished before the feature freeze. Thus, this applet will be merged back into kdebase for KDE 4.7. In the meantime this standalone package has to be used instead. Reproducible: Always
In tree, thanks!
