video illustrating the issue

To reproduce: run the installer (I tested with the 2015-02-04 Rawhide Workstation nightly, you'll need to boot with enforcing=0), enter the time/date spoke, pick a spot on the timezone map, and just keep clicking it.

With every single click, the pin moves. *Sometimes* the city that's selected changes, but not on every click. It usually stays in a relatively small area and flips between one or two cities, but sometimes it goes really nuts (in the video I think it jumps to Moncton once and Winnipeg once, both a timezone away from where I'm clicking).
