xfce4-power-manager using up CPU

My XFCE desktop has become really sluggish after a recent 'pacman -Syu'. It looks like there's a problem with xfce4-power-manager, which appears to be constantly using around 15% CPU and eating up memory at a rate of about 1MB/second - currently at 1GB on my system right now.

Looking at 'journalctl -l --no-pager' I see lots of entries like this:

Nov 27 15:44:22 caolan-laptop dbus-daemon[1040]: [session uid=1000 pid=1040] Successfully activated service 'org.freedesktop.Notifications'

So it looks like there's an issue with xfce4-power-manager showing notifications?

It looks like xfce4-notifyd is not running:

[caolan@caolan-laptop ~]$ systemctl --user status xfce4-notifyd

   Loaded: loaded (/usr/lib/systemd/user/xfce4-notifyd.service; static; vendor preset: enabled)

I killed xfce4-power-manager and then ran it and /usr/lib/xfce4/notifyd/xfce4-notifyd manually and everything seemed to work fine.

Re: xfce4-power-manager using up CPU

I've had the same problem and the same manual solution worked, so how can I find out why xfce4-notifyd isn't being brought up automatically, or just running when it's intended to be?
