[Pkg-ayatana-devel] Bug#930572: vala-panel-appmenu-common: Global Menu doesn't work for GTK applications

[Evgen]

Package: vala-panel-appmenu-common
Version: 0.7.1+dfsg1-1
Severity: important

Dear Maintainer,

On Debian 10 vala-panel-appmenu is mostly unusable because
it doesn't get menus from any GTK2/GTK3 applications.
I tried xUbuntu 18.04 and xUbuntu 19.04 to confirm that
it works properly there.

How to test with XFCE Desktop Environment:
1) sudo apt -y install xfce4-panel-appmenu
2) Add  AppMenu plugin to your panel
3) Log-Out
4) Log-In and start "Thunar"

Expected result:
- Application name appears on the panel
- Menu gets removed from application and appears on the panel

Actual result:
Application name is on the panel but menu stays on the application

------
I looked at the ~/.xsession_errors on both systems:
On Ubuntu:
dbus-update-activation-environment: setting GTK_MODULES=appmenu-gtk-module
dbus-update-activation-environment: setting UBUNTU_MENUPROXY=1
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface
“com.canonical.AppMenu.Registrar” on object at path
/com/canonical/AppMenu/Registrar

On Debian:
dbus-update-activation-environment: setting GTK_MODULES=gail:atk-bridge
* no info about appmenu-gtk-module
* no info about UBUNTU_MENUPROXY
* same error as on xUbuntu
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface

------
Installing MATE. We'll report later if it works there.
