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?
