I don't know what exactly causes this problem in your kde environment,
so I can't tell you how to fix it. I run i3-wm myself, it was no problem
there. You could start a different Gtk+ 3 program from the command line
and see whether it outputs the same Gdk warnings, that way you could
find out if this is an application-specific problem (I doubt it).

Apart from that, I don't really know how to help you. It might be that
the way you run the dialog is not how one should do that, but I haven't
written any programs using gtkmm in some time and don't know whether I
ever did Dialogs it in a different way.

If you get the same warnings in other programs though, I think this
looks like a theme problem. I don't know why, but in my experience (from
1-2 years ago, admittedly), Gtk+ themes can really mess with Gtk+
applications, to the point where selecting a theme that is only
supported for an older Gtk+ version prevents a program from starting.

I don't know if something like that was set up by now, but the gtk-devel
mailing list thread about this topic should hold enough information
about this specific deprecation:
