I have successfully build 'meta-gnome-core-shell' using jhbuild.
But when I run 'jhbuild run gnome-shell --replace', I get following error:
'(gnome-shell:13391): GLib-GObject-WARNING **: specified class size for type 'GnomeShellPlugin' is smaller than the parent type's 'MetaPlugin' class size
(gnome-shell:13391): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed
Gtk-Message: Failed to load module "canberra-gtk-module"
W: [pulseaudio] caps.c: Normally all extra capabilities would be dropped now, but that's impossible because this Pulseaudio was built without libcap support.
