search provider / search bar integration has stopped working

[Christian Pernegger]

Previously, I could call up Gnome's desktop overview[?], e.g. via the Windows key, and type a simple calculation straight into the search bar on top. Gnome calculator would then provide the result of that calculation as a "search result", and give me the option to copy it to the clipboard or start gnome-calculator proper and continue working with it.

Currently, typing numbers and/or operators into the search bar will not trigger gnome-calculator any more, as if its search provider was disabled. (It's not, I triple-checked.)
