Please create a bug fix release, so distro users eventually can take advantage. Example: See #12292 where the downstream maintainer is waiting for it: https://bugzilla.redhat.com/show_bug.cgi?id=1278772#c8
1.6.0 was released a little while ago http://git.xfce.org/xfce/xfce4-power-manager/tag/?id=xfce4-power-manager-1.6.0 Marked resolved.
Thanks Eric for pointing out. Downstream bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1339335
