Updating Fedora 38 to 39 breaks octave-8.3.0 (precompiled from Fedora) and
octave-8.4.0(compiled from source). When I run

$ /usr/bin/octave --gui

(octave-gui:1632543): Gtk-WARNING **: 18:58:40.527: Theme parsing error:
<data>:1:0: Expected a valid selector

and the window hangs.

The font initialisation appears to be rewritten for Qt6 in octave-9.0.0 from
the mercurial repository and it works OK. 
I think this bug is discussed at:

https://bugreports.qt.io/browse/QTBUG-112896

The maintainer doesn't intend to fix it. I will look forward to the release of
octave-9.1.0 in December 2023.

Here is a backtrace:
