OK, I found it. Looking upstream & looking at the gnome CVS for gnome- control-centre/gnome-keyboard-properties, I found a reference to http://bugzilla.gnome.org/show_bug.cgi?id=398631. In there, there is a comment that a similar segv is caused by a missing file -- desktop_gnome_peripherals_keyboard_xkb.schemas. This file is installed by libgnomekbd-common -- which *is* installed in my machine.
BUT -- the file is not there. So I reinstalled libgnomekbd-common, and the segv went away. So, for me, this seems to have been fixed upstream by 398631. Why the schema was not installed... is a question I am unable to answer right now. But the bypass is to re-install libgnomekbd-common. -- segfault in gnome-keyboard-properties https://launchpad.net/bugs/82373 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
