I believe it is a pkg that allows you to mount/automount an MS ntfs/dos partition properly.
All gvfs pkgs relate to automounting for filemanagers etc. It is the first thing I remove on any system I install.
You can use cower to get gamin from aur, glib2 is its only dependency.
Chroot into the mounted partition you are installing to
sudo arch-chroot /mnt (or whatever your installation's mount is)
cower -d -t /tmp gamin
cd /tmp/gamin
makepkg
sudo pacman -U gamin-0.1.10-9-x86_64.pkg.tar.xz
gamin is needed by smbclient and mpv/smplayer
