Actually the issue goes away if I remove the installer-included GTK runtime, so that the one in PATH is used. I guess I didn't add enough files (icons?) to the installer
Indeed, I could fix the lacking icons and the warning spam by including the adwaita icon theme into th installer.
A terminal window still opens when I launch geany and GTK prints some warnings, but only at startup.
Best regards
