Dbus message lost

[Pradeep Khannan]

Hi,

I wrote a sample application, included in this email, to test invoking an
application on a dbus message. I can see that the application launches but
the dbus message that launched the apllication never reaches the filter
method. Could you guys please help me with this.

Thanks,
Pradeep
