Edit Connections, Wireless tab, Add button to open the "Edit wireless connection" dialog. Go tot IPv4 settings tab. Clicking the "Routes..." button closes both dialogs.
The same button on the "Edit wired connection" dialog works.
And the same button on the "Edit vpn connection" dialog is broken in the same way.
Fixed upstream last week (applet svn r914), will grab this when I pull new updates into rawhide.
I lied; fixed now in applet svn r921
