I can reproduce the steps listed, marking as confirmed

It also fails if you try to execute gnome-control-center on a headless computer, I don't see how this could affect someone, it seems gnome-control-center setup everything before reading parameters and print something, probably will take them a reasonable effort (or hack) to make an exception for --version.

that's only the version flag from a command line, not really an important issue no, setting to low
