Is ico-homescreen a QT5 app? Are you trying to run it under Gnome-Shell Wayland, or Weston? I think there is a problem with wl_shell and gnome-shell which is what QT5 applications currently use by default, (as opposed to xdg_shell) and I get protocol errors... 

...I don't know if it's a problem with gnome-shell, or qtwayland, as QT5 applications do run on Weston, but this reminds me that I probably should discuss who to report it to on IRC,.

If you are getting these errors on gnome-shell, it's probably the same thing I noticed, but forgot to report.
