   Returns the connection that sent the signal, if called in a slot activated
   by QDBus; otherwise it returns 0.

+  \note Please avoid this function. This function is not thread-safe, so if
+  there's any other thread delivering a D-Bus call, this function may return
+  the wrong connection. In new code, please use QDBusContext::connection()
