No. I know about that one :)

ah, and as I write this I see Antonio has solved it :)  \o/
But we still have issues....

Yes, used that - happy with osso_initialize()

I actually would like to know what osso_initialize() should do so we can do the
right things in a Qt app though.

And your name appears a lot in the source Kimmo :)

OK - but do you have a list of things that we should do to make Qt equivalent to
gtk?

I seem to recall things like dbus messages on low memory and others. Are these
documented?

The banner would be nice - but the dbus services listed above don't seem to be
correct - and I can't find them using a dbus introspect (qdbusviewer)
ie this bit (from original email)

Are you in a postion to help us write the Qt equivalent of osso_initialize() and
help make Qt == Gtk
