It seems this is not working for any gtk+3 application. While xterm
works as described in the xdotool manpage a simple:

    zenity --entry --title xsendeventtest &
    xdotool type  --window $(xdotool search "xsendeventtest") asdf

does not work here either. Maybe the gtk+ maintainers have and idea how
to get this working?

Can you point me to the code you run the tests with? You should be able
to use the same mechanism with libvirt as without it.
