Hi Andreas,
The check was originally placed there by Paolo for -object handling.
We need to find out where the "qom-type" property is coming from. (What code is

If is added automatically at parse/init time we can't get rid of it.
If is object specific, it is ok.
Paolo, can you please advise?
Thanks,
Marcel
