Ah my bad, indeed only a warning is issued for a misplaced
property (the warnings which the Bernhard originally mentioned).

Agreed, however while Glade is usually behind GTK+ in terms of features
so often times Glade chokes out on hand crafted GtkBuilder xml which might
contain tags that Glade does not yet recognize.
But the opposite should usually never be a problem, unless we introduce
features with some severe bugs then files created by Glade should always
be readable by GtkBuilder (in this case we introduced GtkGrid with a bug
that at least only causes a warning... unless there is more to this
GtkGrid story...).

Indeed, I'm not sure what is the story with GtkGrid not showing the content
when loaded in a preview or an application (and the preview quite litteraly
does what an application would do).
Bernhard, can you perhaps attach the Glade file in question which does
not show the contents of the GtkGrid ?
