Well, so I don't think there's really a bug here, same kind of thing would
happen when opening that folder in Thunar anyway, it's just that template dir
is a bit special because it will happen every time Thunar is started. By the
way, does it happen every time a Thunar window is opened or only when the
Thunar daemon is started?
Also, the behavior might have slightly changed with the GTK-3 rewrite.
In any case, it looks to me like a case of “it hurts to do that, so don't do
it”. If you need templates, then have a specific folder with only the
templates files you need. If you don't, the way to disable it is supposedly to
set it to $HOME using:
xdg-user-dirs-update --set TEMPLATES ~
or editing .config/user-dirs.dirs
