I have seen a number of issues related to this error message. Including slow wake up from sleeps. Long pauses in screen repaint. Long launch times for applications. The only sure fix I found was to completely purge the gnome-shell-extension-appindicator package and reboot. The system them becomes properly responsive again. I have no idea what visual flim flam this extension provides so I can certainly do without it. It is a shame that it is installed by default.
