    Bug 24235 – polkit-agent-helper may call pam_end with a stale pam handle
    
    polkit-agent-helper calls pam_end on pam_h without setting pam_h to
    NULL. This causes the error handler to call pam_end on the stale
    handler if the send_dbus_message procedure fails, which in turn
    generates a SIGSEGV.
