Uh-uh, Erik.
It re-opened on those same 4 items again, despite deleting those 4 lines. They haven't been re-created, though.
I suspect this may have been my own fault. I deleted all that stuff in /var/cache/fontconfig from outside KLV, followed by manually adding all the new fontconfig stuff you put in that tarball. Of course, like this, the fc-cache never got updated by the system did it? I probably deleted summat important. Trying to re-start XFCE4, I got tons of stuff about "libupower", "Glib-GObject", "GDBus" (dbus seems as though it simply couldn't start, period).....
Self-inflicted, methinks.
I'm currently attempting a restore from the most recent backup I made. Let's see what happens. I'll report back tomorrow; it'll take a while to restore, 'cos it's got to copy back all those excess fontconfig files. I'll see if she'll get to desktop, THEN I'll see about clearing stuff from inside KLV, so the system knows what I'm doing.....
Never rains but it pours, eh?
Mike.
