Dear Maintainer,

   * What led up to the situation?
The bottom panel of gnome-flashback is empty

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
If I try to add an item to it (via Alt-Right click) --> Add to panel, it shows
the items list but when I click "Add", nothing happens

   * What was the outcome of this action?
No Item added to the bottom panel

   * What outcome did you expect instead?
The selected item added to the bottom panel
---

If I issue "gnome-panel --replace" I get this ouput:

Hi all,
Both the bugs seem to be saying the same thing.

I just tried to run gnome-panel --replace in my gnome-flashback
session and came up with this :-

$ gnome-panel --replace

(gnome-panel:13588): Gtk-CRITICAL **:
gtk_accelerator_parse_with_keycode: assertion 'accelerator != NULL'
failed

** (gnome-panel:13588): WARNING **: Unable to parse mouse modifier '(null)'


(gnome-panel:13588): GLib-GIO-CRITICAL **:
g_dbus_connection_call_internal: assertion '(parameters == NULL) ||
g_variant_is_of_type (parameters, G_VARIANT_TYPE_TUPLE)' failed

and it just hangs in there.

There are no panels and can't do anything except do :-

gnome-session-save --kill --silent

I cannot reproduce this, even with a fresh setup. Can you please try
resetting the configuration and see if that helps?

gsettings reset-recursively org.gnome.gnome-panel

Hi all,
As I have the same/similar issue, I tried the above :-

$ gsettings reset-recursively org.gnome.gnome-panel

I had to reboot and in new session it was the same thing, wasn't able
to add anything to the bottom panel. I tried the 'window list' applet
and no sugar for me.

One thing to note though - the notification area which had disappeared
in the top-panel returned, apart from that no change.

I ran

$ gsettings reset-recursively org.gnome.gnome-panel

and it removed all panels (top and bottom)

then I ran

$ gnome-panel --replace

and went back to the same scenario (top panel ok, bottom panel empty and
still can't add items), with this output:

Can anyone confirm if this still happens with gnome-panel 3.38 or newer?
