I've had this issue for a while but held off on reporting it since I was using a pretty old ISO. After a fresh install from a 20150128 Freya ISO I still have the bug.
If I type in the path bar and hit enter, nothing happens. Then when I click outside of the path bar, the path bar updates to look like the path I tried to go to, but Files does not go there.
