I will try to explain better:    when I run my application for the first time it will start geoclue-gpsd provider automatically. Then everything is ok, I can use my application properly. When I close my program I have noticed that geoclue-gpsd remains alive (as expected). Then, if I try to restart my application again I have this problem: Using provider 'Gpsd' Error getting position: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. But, if I kill geoclue-gpsd and I restart my application everything is ok. <div class="gmail_quote">On Thu, Apr 17, 2008 at 1:12 PM, Jussi Kukkonen <<a href="mailto:jhkukkon@cc.hut.fi">jhkukkon@cc.hut.fi</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div class="Ih2E3d">Emanuele Leomanni wrote: > I have seen that when I run my application developed using geoclue API all > providers needed are executed automatically. </div>The automatic shutdown didn't really work as intended (see my status update post couple of days ago): I'm currently working on this on "refcount" git branch, will post a mail about it soon.

As a matter of fact there could be NO_AUTO_SHUTDOWN option (either compile- or run-time) if that's wanted. Are you sure the dbus autostart works? In other word, you're not starting the provider by hand in the first place? Jussi </blockquote></div>
