I'm not sure about what qtengine is, but I'll guess: Choosing "Use my KDE style in GTK applications" on the appearance settings, section "GTK Styles and Fonts", make-frame-on-display produces a segfault, as reported. Choosing "Use another style: Raleigh" works fine, except for this message on the console: (emacs:12482): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed just after `delete-frame' on the frame created with `make-frame-on-display'. I'm working on Kubuntu 8.10 x86_64 KDE 4.2.2. Hope this helps. -- Oscar

This sounds very much like a very long standing Gtk+ bug: http://bugzilla.gnome.org/show_bug.cgi?id=85715 we have had a few bug reports in emacs about it. You could verify that by configuring emacs with --enable-toolkit=lucid I think we should have a big warning in NEWS pointing to that Gtk bug and saying that if people want to connect/disconnect to X11 display, they'd better avoid using Gtk.
