"Last Modified: Unknown" in statusbar for not 1 file selected
I just built 4.19.2git-be16f77d and noticed that when no files are selected in a folder, or several files are selected, I see "Last Modified: Unknown" in statusbar.
(If I go one level up and select that directory, or if one file is selected, I see a modification date).
I did patch the Thunar code a bit but I don't think it was the cause.
