Hey Brian, I was going to let this run longer, but I think we're safe. I've observed RSS of both xfce4-power-manager and NetworkManager grow by over 1.5MB from usage at start up and have now dropped back to more than 1MB below usage at start up. These observations were made with swap disabled, so they should be accurate. Without the patch, both would be ~50MB over start up usage by now.

I've built the package with it locally and confirmed that it fixes the leak in xfce4 -power-manager, which is mentioned in the upstream report. It also fixes a similarly sized (hundreds of MB after a few days up time) leak that I have observed in the NetworkManager service. [Impact] Hundreds of MB memory leak in certain dbus applications, including default services like xfce4-power-manager and NetworkManager with default configurations. [Test Case] Clean install of lubuntu 15.10 on a notebook with working battery. Observe xfce4-power-manager and NetworkManager* in "top" over 48-72hrs of normal use (web browsing, text editing, shell, etc). Both will be taking on several tens of MB per day of additional RES. *NetworkManager may require buggy wifi to reproduce. rtl8723be in my case. [Regression Potential] I'm no authority on the glib code base, but the upstream patch looks very safe to me. Let me know if you need any further details.
