Segmentation fault when using upower and playerctl interfaces

[VentGrey]

Hello lgi development team. I've encounteded an issue with both lua and luajit when trying to use the playerctl and upower interfaces. The output itself is not very descriptive as the command line only reads `Segmentation fault".

I don't even know where to start as it is easy to get lost, I've made the following upower example code to explain:

local upower = require("lgi").require("UPowerGlib")
local devices = upower.Client():get_devices()

The same happens with playerctl:

local lgi = require("lgi")
local Playerctl = lgi.Playerctl
local player = Playerctl.Player{}

print(player:get_title())

I think I have all the needed introspection objects needed. Placing such code inside a GLib main loop doesn't change the output at all. Any ideas on what might be happening?

local upower = require("lgi").require("UPowerGlib")
local devices = upower.Client():get_devices()

Here it works without any segmentation fault (lua 5.4.4, lgi master).
