[arch-general] upower.service stop working

[Zhengyu Xu]

Dear all,

Today I suddenly found the battery-icon disappeared from
my gnome-shell panel. When I checked the status of
systemctl there is a failed item corresponding to
upower.service. Followings are the output of "systemctl
status upower.service":
power.service - Daemon for power management
	  Loaded: loaded (/usr/lib/systemd/system/upower.service; disabled)
	  Active: failed (Result: signal) since Fri, 03 Aug 2012 00:48:40
+0900; 2min 57s ago
	 Process: 4270 ExecStart=/usr/lib/upower/upowerd (code=killed,
signal=SEGV)
	  CGroup: name=systemd:/system/upower.service

and relevant output from "journalctl":
Aug 02 23:39:37 xzy3186-E420 systemd[1]: upower.service: main process
exited, code=killed, status=11
Aug 02 23:39:37 xzy3186-E420 systemd[1]: Unit upower.service entered
failed state.

I don't know how to get more debug information to this problem.

Is there anybody else who also has similar experience? I will appreciate
very much if someone could give me any suggestion.

Best regards,
Zhengyu

PS: My environment is
upower-0.9.17-2
systemd-187-4
