Created attachment 7251 
not shure is is good enough for other , but here works for build

first thing:
[quait@AMD-PHENOMII ~]$ xfce4-mixer &
[1] 17931
[quait@AMD-PHENOMII ~]$ 
(xfce4-mixer:17931): xfconf-WARNING **: Unable to transform the value of property "controls" from type "GPtrArray" to "GPtrArray_GValue_".

(xfce4-mixer:17931): xfconf-common-WARNING **: GType GPtrArray_GValue_ doesn't map to an Xfconf type

(xfce4-mixer:17931): xfconf-common-WARNING **: Unable to convert GType '(null)' to GVariant

[quait@AMD-PHENOMII ~]$

is there a problem by xfconf or other's, 

Please give me a dubuging-instruction, to find out!

Regards   

two:
just with the attached patch, my builds will use keybinder-0.3.0
no other way's found by many tested changes on the configure.ac.in
