Bug Description

in gnome-panel (gnome-flashback) there is an icon for hp-printer (looks like part of indicator-applet), if i click it, a menu is shown, but no readable menuentries. i tried to make screenshot while menu is open, but menu is not visble on this screenshot (seems like it is some kind of overlay).

Use Screenshot application to create screenshot. Choose "Grab the whole screen", set few seconds as delay, press "Take Screenshot". Open menu and and after delay screenshot will be created.

From quick look this might be problem in indicator-application...

Looks like hplip trayicon first is created without menu, "/NO_DBUSMENU" is set as "Menu" for status notifier item. Then it is updated to correct menu path, but indicator does not recreate menu.

D-Bus menu is created only when application is added:
https://git.launchpad.net/ubuntu/+source/indicator-application/tree/src/indicator-application.c#n555

As workaround use `systemctl --user restart indicator-application.service` to restart indicator application. Then it will pickup / use correct menu path.

Don't know... This needs to be done after hplip tray icon is added/started.

the hp-tray-icon is started via gnome startup-applications

on console (after killing the tray-application) this works:

hp-systray -x & sleep 15 && systemctl --user restart indicator-application.service

but if i modify the existing entry to this command-line it does not (maybe this is not executed via shell). i put this into a bash-script and changed the startup-entry to this..now it works

as far as i understand you this is still a problem in hplip or more indicator-applet?

I think real bug is in indicator-application. Definitely not in indicator-applet as it only loads various indicators. I guess it could be fixed also in hplip... For some reason menu is set after some delay - https://git.launchpad.net/ubuntu/+source/hplip/tree/ui5/systemtray.py#n359

i guess delay is for checking printer-status first before building menu...atm i can live with the workaround, but it should be fixed :) thank you very much
