Trying to step through this with gdb.

In main(), control-center.c:254 the following statement

shell = gnome_control_center_new ();

assigns NULL to shell, after emitting a few warnings:

(gnome-control-center.real:653): GLib-GObject-WARNING **: cannot derive 'GnomeControlCenter' from non-fundamental parent type 'CcShell'

(gnome-control-center.real:653): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed

(gnome-control-center.real:653): GLib-GObject-CRITICAL **: g_object_new: assertion 'G_TYPE_IS_OBJECT (object_type)' failed

which then causes a segfault later, when it's dereferenced.

I can reproduce this by creating a new user account (sudo adduser guest) and logging in.

I cannot reproduce this by booting Ubuntu GNOME 14.04 LiveCD.

Ok, turns out I hadn't actually purged all the PPA packages correctly, and so I somehow ended up with gnome-control-center 1:3.6.3-0ubuntu56 but libgnome-control-center1 1:3.10.1-0ubuntu1~saucy3 .

After I downgraded the former gnome3-team/gnome3 PPA packages to their versions in trusty, this problem no longer recurs.

The command I used was

sudo apt-get install $(apt-show-versions|grep 'newer than version in archive'|cut -d ':' -f 1|sed -e 's/$/\/trusty/')

Thanks Marius Gediminas, this has worked for me! (Just updated from 13.10 to 14.04, had other Gnome issues as well).

Marius, thank you for taking the time to resolve this for the rest of us. Using Synaptic, I just downgraded libgnome-control-center1 1:3.10.1-0ubuntu1~saucy3 to 1:3.6.3-0ubuntu56 (with Package->Force Version), and it runs now.

Downgrading the library 1:3.10.1-0ubuntu1~saucy3 to 1:3.6.3-0ubuntu45 fixed the issue for me too.

This bug has been marked against package ppa-purge. Did you guys try to purge the PPAs by ppa-purge before upgrading to Trusty? I don't see why you had greater version of libgnome-control-center1, if you did.
