[Lxde-list] lxpolkit warning on each lxde session startup

[YUP <yup...@gm...>]

I compiled lxpolkit form git, and now every time whan I log in to the lxde
session I have the following worning:
Remote Exception invoking
org.freedesktop.PolicyKit1.Authority.RegisterAuthenticationAgent() on
/org/freedesktop/PolicyKit1/Authority at name org.freedesktop.PolicyKit1:
org.freedesktop.PolicyKit1.Error.Failed: Error parsing subject struct
org.freedesktop.PolicyKit1.Error.Failed Error          0xb777aaa0arsing
          \Uffffffff\Uffffffffubject
 0h\Uffffffff\Uffffffff\Uffffffff\Ufffffffftruct

IS THAT SERIOUS?
