This is a packaging issue. The icon for "missing", which is in package gnome-icon-theme, MUST be installed with GTK. The icon for "missing" is the fallback icon for GTK whenever it can't find an icon. If GTK package does not depend on gnome-icon-theme, then GTK will crash when it needs the icon for "missing."

I am a developer running a Gimp plug-in (Python) in the Gimp app. Opening a Gtk.FileChooserButton widget. Expected widget to appear. What happens: widget is garbled and console shows: Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Icon 'image-missing' not present in theme Symbolic (gtk-icon-theme-error-quark, 0) with a stack trace and opportunity to exit the plugin. Gimp continues to run (since plugin is separate process.) See the issue filed against Gimp: https://gitlab.gnome.org/GNOME/gimp/-/issues/2029. That report is on Gimp in Ubuntu 18.04. Still present with the latest Gimp (built myself) on Ubuntu19.04. Installing the package gnome-icon-theme fixes the issue. As reported in Gimp #2029 It might be a packaging issue: a missing dependency of the gtk3 package on package gnome-icon-theme. Since package Gtk3 can crash unless gnome-icon-theme is also installed. Probably it is a weakness of Gtk3, and would best be fixed there. I.E. its a circularity issue: Gtk3 should not depend on an "image-missing" icon being in a theme to resolve the problem of an icon missing from the theme. Or the Gtk3 developers have failed to convey a dependency to distributors like Ubuntu.
