I have the same problem, but I discovered it opens directories inside $HOME.
I.e. Alt+F2 'wesnoth' opened a nautilus windows with the directory /home/manolinux/wesnoth , wich happened to exist. It works with any directory inside $HOME. Since it is said to be resolved in 3.2 version, I don't know if it is still relevant, but I find it curious at least :) -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
