crashes switchboard when plug first opened

[Sam Thomas]

Clicking on the power plug in switchboard immediately crashes switchboard. This is the stacktrace:

[FATAL 16:20:26.191107] [Gtk] gtk_widget_set_visible: assertion 'GTK_IS_WIDGET (widget)' failed
[FATAL 16:20:26.193852] power_upower_device_Refresh: assertion 'self != NULL' failed

it happens to me, but, I think it is deuplicate of this report

i think this is not a duplicate of the bug you provide. here the error is about upower devices, dbus connections. the other is about gsettings schema's those are different.

@Sam are you running an official released build of elementary os?
if so could you provide the full output of the following command:

"switchboard -d power"

thank you in advance

I am running the official development version of Loki. I am running the latest version of the power plug which is 0.2.2+r306~daily~ubuntu0.4.1

Here's the output of "switchboard -d power"
