I was trying to reproduce https://bugzilla.gnome.org/show_bug.cgi?id=554366 with an actual Files, and I found a very similar bug (that’s why I post in “File and Folder Operations”, I think it’s the same problem), with quite more impact. I’m in 3.5.92.

* You have to be in list view (as the other bug…)
* Go in your home folder (or elsewhere, it doesn’t matter here…)
* Create a folder (ctrl-maj-n), name it "a", go into "a"
* Create a folder (ctrl-maj-n), write the name "b" but without validating
* Use the path bar to go back to your home folder

At this point, you cannot open any file or folder in your home, neither with mouse nor with keyboard. You equally have some strange behaviour after having tried to rename, and in some cases, if you delete "a" and recreate it, "b" is always here.
