After upgrading to 2.1.2.3 my GPS stopped working. After a short debug session, I noticed that the geoclue-hybris is not launching. It fails to launch because of this:
/usr/libexec/geoclue-hybris: symbol lookup error: /usr/libexec/geoclue-hybris: undefined symbol: _ZN14NetworkService9connectedEv

Which library should provide the symbol mentioned above? I wonder if I have a wrong version of some package?

I can work around the problem by disabling the Mozilla-thingys in positioning settings.
