Arch Linux

Description:
After installing the xfce4 group, starting an xfce4 session starts an xfce4-power-manager process that is unresponsive and slowly grows its memory footprint without an obvious bound. (top showed >50% memory usage on my 4GB system after a few hours.) Based on the output in the console after I killed that process and started xfce4-power-manager from the terminal, it was having trouble connecting to a libnotify-compatible DBus service.

Installing xfce4-notifyd and logging back in fixed the issue: I can open the settings menu and my memory isn't being devoured. It would be nice if the xfce4-power-manager package had an optional dependency on xfce4-notifyd to hint future users to install that package too.

Additional info:
* package version(s): xfce4-power-manager 4.16.0-1
* config and/or log files etc. - N/A, cannot configure with xfce4-power-manager-settings because the manager process is unresponsive.
* link to upstream bug report, if any - N/A

Steps to reproduce:
- Install the xfce4 group, don't install xfce4-goodies or xfce4-notifyd.
- Possibly related: have other desktop environments installed (I have fvwm, fluxbox, awesome, i3, lxqt, openbox, plasma, and sway in addition to xfce4.)
- Log in to an xfce4 session.
