Subject: cinnamon-settings segfaults on entering power settings applet

Date: Fri, 17 Jun 2016 08:17:52 +0200

Package: cinnamon
Version: 3.0.4-1
Severity: normal

Dear Maintainer,

cinnamon-settings throws a segmentation fault whenever I try to open the power settings,
be it from the panel applet or the settings window.

Steps to reproduce:
1. open "cinnamon-settings" in terminal
2. enter the power settings
3. EXPECTED: you have the power settings applet
   HAPPENS: window closes, you get segmentation fault:

$ cinnamon-settings                                                                                                                               [0] 16-06-17 8:01
Loading Power module
[1]    (PID) segmentation fault  cinnamon-settings


(tested on a clean boot, with the same result)

Power management was working about a month ago or so - possibly a regression.

I'm using systemd 230-2 and upower 0.99.4-3.
Hardware: Lenovo Thinkpad W500.

This is caused by a change in the libupower-glib3 0.99.4-3, installing the 
0.99.4-2 version fixes the issue.

I'm cloning the bug to notify the upower maintainers about it.

Currently the cs_power module uses the gir interface doing:
import gi
gi.require_version('UPowerGlib', '1.0')
from gi.repository import UPowerGlib

up_client = UPowerGlib.Client()
has_lid = up_client.get_lid_is_present()
------------

With the new version that snippet segfaults. I'm not well versed in the gi 
internals but it seems to me that UPowerGlib.Client() is not creating a new 
instance, probably related to the fact that it used to be a singleton, I'm not 
sure.

Using the similar version:
import gi
gi.require_version('UPowerGlib', '1.0')
from gi.repository import UPowerGlib

up_client = UPowerGlib.Client.new()
has_lid = up_client.get_lid_is_present()
-------------

Works as expected in both versions, so I'll probably patch this in the next 
upload if it's not fixed in upower by then.

Happy hacking,
