unity-panel-service crashed with SIGSEGV in atk_object_get_n_accessible_children()

[C Schilder]

Earlier today I experienced another bug. The login loop from LightDM. Fixed it with the 'disable login-sound' workaround, and still works fine.
This crash is new for me. Just logged into Ubuntu, right away it gave me a crash report detected notify.
Haven't started doing anythin yet.
