Hi Ian, Thanks for reporting.

I checked this some and I think the problem lies in function org-show-notification. That function references and possibly uses function notifications-notify which depends on a proper setup of the dbus stuff. I guess this is the gist of the bug. You can place your own handler though. For this set variable org-show-notification-handler to e.g. function message Can you please try this out? About hunting the bug: possibly it would be good to add a check if the dbus system is up. Can this be done easily? Or add a further configuration item to indicate that the dbus system shall be used. Best, -- Marco
