maemo.org - Talk - Launching application using DBus

I'm having problems launching my application (cuteTube) using DBus in MeeGo-Harmattan. The application launches, but the arguments of the method call are not received. If I use the same method call when the application is already running, it works as expected. I'm using qdbus to test e.g.

Code:

qdbus com.marxian.cuteTube / com.marxian.cuteTube.play <video_url>

Here's my interface XML file:

Code:

<node>

    <interface name="com.marxian.cuteTube">

    <method name="play">

        <arg name="url" type="as" direction="in" />

    </method>

    <method name="display">

        <arg name="url" type="as" direction="in" />

    </method>

</node>

Here's my service file:

Code:

[D-BUS Service]

Name=com.marxian.cuteTube

Interface=com.marxian.cuteTube

Exec=/usr/bin/single-instance /opt/cutetube/bin/cutetube

Looking at some of the other service files in /usr/share/dbus-1/services, I see that some have a fixed argument in the Exec value, but other than that I cannot see any difference.
