[Evolution] GPS Coordinates

[Rudolf Künzli <rudolf kunzli gmail com>]

Evolution 3.24.4 Fedora 26

I entered the GPS coordinates into one of my contacts and clicked on
"Open Map" to verify it.
Unfortunately it didn't work out from here.
It works fine when I use it from Google Contacts (server) directly.
After some investigation I found out that in Evolution a comma is added
after the GPS coordinates causing the error!
That comma is not added within Google Contacts (server).
I guess that it's a bug in Evolution.
Any ideas?
