and apparently don't set the property.

This messages appears to originate from gtk_builder_value_from_string_type in gtk/gtkbuilder.c. This function seems to be responsible for converting the strings coming from XML to actual values, and it only knows about the common value types. I don't see any hooks to customize this process. Not even providing a SET_BUILDABLE_PROPERTY override would be sufficient. I think you'd need to have a custom tag for this, handled in a CUSTOM_TAG_START override.
