Bug#710094: gnome-panel: Top panel became a black blank bar after last libgnome upgrade in jessie./testing

[Tianming Xie]

Package: gnome-panel
Version: 3.4.2.1-5
Followup-For: Bug #710094

Dear Maintainer,

After last upgrade of libgnome-menu-3-0, the top panel became a black blank bar, with application menu, clock, and applets disappeared. When "gnome-panel --replace" is invoked, it produces outputs as below:

(gnome-panel:25930): Gtk-CRITICAL **: gtk_accelerator_parse_with_keycode: assertion `accelerator != NULL' failed

** (gnome-panel:25930): WARNING **: Unable to parse mouse modifier '(null)'


(gnome-panel:25930): GLib-GObject-WARNING **: /tmp/buildd/glib2.0-2.36.3/./gobject/gsignal.c:2475: signal `size_request' is invalid for instance `0x1b22bf0' of type `GtkLabel'

Interestingly, this problem only appears on boxes using nouveau and radeon display drivers as far as I know. On
 a Dell Latitude D430 with Intel 945GM (using driver i915), gnome-panel works fine.
