[Robert Thompson via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

Starting 'emacs', even 'emacs -Q', from the command line (eg a Terminal session) now givesthe following warning:
You are trying to run Emacs configured with the
"pure-GTK" interface under the X Windows System. That confituration is
unsupported and will lead to sporadic crashes during transfer of large
selection data. It will also lead to various problems with keyboard
input.
Install emacs-gtk+x11 or emacs-lucid package.


But the packages are already installed:
$ sudo dnf install emacs-lucid

This started after I upgraded to Fedora Linus 40 (Workstation Edition)
