Xfce Power manager memory leak in Xubuntu Xenial daily?

I'm running the 20160115 daily xubuntu build, xenial-desktop-amd64, live from a usb drive. The Xfce4-power-manager package (version 1.4.4-4ubuntu2) seems to have a memory leak, consuming all 4GB of RAM when running for more than an hour on a Core i3 system. I've never seen this in any previous xubuntu release.

Task Manager reports the task as
"/usr/lib/x86_64-linux-gnu/xfce4/panel/wrapper-1.0 /usr/lib/x86_64-linux-gnu/xfce4/panel/plugins/libxfce4powermanager.so 5 8388654 power-manager-plugin Power Manager Plugin Display the battery levels of your devices..."
