If you start gnome-terminal in gnome, and then log out saving settings,
when you log in again the window title is blank (and shows up as '???' in
gnome-terminal code looks correct to me; this is likely a session manager
or gnome-libs problem. Needs a fairly in-depth investigation.
any progress here?
It works for me in Rawhide if you set the title with the --title command line
if you set the title with terminal escape sequences it deliberately doesn't
remember the title, since this is typically used to report current directory.
