Log Message:
Fix segfaults when upower is not running.
On my system, these patches stop xfsettingsd (from XFCE) from crashing
and dumping core during session startup. Thus, it can actually apply the
settings it is supposed to.
I just wish upstream had done a bugfix release, the patches are from 2016 :(
Fixes PR pkg/53455, which I filed :)

+Subject: [PATCH 1/9] lib: Add proper error and cancellable handling to
+ UpClient constructor
+
+A GObject's _init() should never fail or block, but this is currently the case
+as up_client_init() connects to upowerd on D-Bus. Convert this to the GInitable
+interface and provide a new constructor up_client_new_full() which accepts a
+GCancellable and GError, so that clients can do proper error handling
+and reporting.
+
+This changes up_client_new() to return NULL when connecting to upowerd fails.
+This provides a more well-defined behaviour in this case as clients can check
+for this and our methods stop segfaulting as they have checks like
+
+ g_return_val_if_fail (UP_IS_CLIENT (client), ...)
+
+Previously we returned a valid object, but trying to call any method on it
+segfaulted due to the NULL D-Bus proxy, so client code had no chance to check
+whether the UpClient object was really valid.

+Subject: [PATCH 2/9] up-tool: Exit early when connecting to upower fails
+
+This avoids spewing dozens of assertions like
+
+ libupower-glib-CRITICAL **: up_client_get_devices: assertion 'UP_IS_CLIENT (client)' failed
+ libupower-glib-CRITICAL **: up_device_get_object_path: assertion 'UP_IS_DEVICE (device)' failed
+
+and useless default values and then exiting successfully (which might confuse
+users or scripts trying to parse the output).
+
+Use the new up_client_new_full() constructor so that we get a proper GError.
