Yes, I think this is a dup of #25228 "custom-set-faces from init file~/.emacs ignored". Does adding (define-key special-event-map [config-changed-event] 'dynamic-setting-handle-config-changed-event) to your .emacs help?
Hi, thanks for the quick reply. It looks indeed like a duplicate of #25228, sorry for not properly checking.
I did the change as you asked, but it didn't help. I also tried the workaround mentionned in the other bug:
and this one made it work (I removed your line).
Just to provide complete information, as it seems the problem is related to Gconf and Gnome stuff, I am using Xfce4 for my X11 environment.
Thanks,
François
