Location broken on Nexus 5 with CM11
Just curious if you use Google device / location manager(s)?

I have had some of theses issues come up on CM11.  

Try going to Google.com then click maps as your search criteria/engine and type ' my current location ' as the search, and also in the map click the little circle in the bottom right corner (its the circle above the blue direction circle ....its the location target eye image , black and white) .....you should be asked if you would like to allow Google to access your location by now.  because if not it could just be a settings thing.  

I suggest using Google chrome when / if you do this.... I had better luck when I did... which makes sense since chrome is a Google entity.

I am not saying this is a fix, but I am curious about the results because this may help myself and others to get an understanding of how your devices current state due to how it handles the request(s).

CM11 hasn't treated me too well in this respect either.
