Clearing a TextView's buffer from a widget inside the TextView sometimes causes a segfault

Steps to reproduce

1. create a TextView
2. create a TextAnchorChild
3. create a Button
4. insert Button at TextAnchorChild
5. have the Button's call back set the TextView's buffer text to ""
6. Segfault (sometimes)

#include <gtk/gtk.h>

static void button_callback(GtkButton* const _button, void* const user_data) {
    GtkTextView* const text_view = user_data;
    GtkTextBuffer* const buffer = gtk_text_view_get_buffer(text_view);
    gtk_text_buffer_set_text(buffer, "", 0);
}

static void show_ui(GtkApplication* const app) {
    GtkApplicationWindow* const window = GTK_APPLICATION_WINDOW(gtk_application_window_new(app));
    gtk_window_set_title(GTK_WINDOW(window), "bug testing");

    GtkButton* const button = GTK_BUTTON(gtk_button_new_with_label("segfault here!"));
    GtkTextView* const text_view = GTK_TEXT_VIEW(gtk_text_view_new());
    GtkTextBuffer* const buffer = gtk_text_view_get_buffer(text_view);
    GtkTextChildAnchor* const anchor = gtk_text_child_anchor_new();
    GtkTextIter iter;
    gtk_text_buffer_get_end_iter(buffer, &iter);
    gtk_text_buffer_insert_child_anchor(buffer, &iter, anchor);
    gtk_text_view_add_child_at_anchor(text_view, GTK_WIDGET(button), anchor);

    g_signal_connect(button, "clicked", G_CALLBACK(button_callback), g_object_ref(text_view));

    gtk_window_set_child(GTK_WINDOW(window), GTK_WIDGET(text_view));
    gtk_widget_show(GTK_WIDGET(window));
}

int main(int const argc, char** const argv) {
    GtkApplication* const app = gtk_application_new("com.example.demo", G_APPLICATION_DEFAULT_FLAGS);
    g_signal_connect(app, "activate", G_CALLBACK(show_ui), NULL);
    g_application_run(G_APPLICATION(app), argc, argv);
    return 0;
}

Current behavior

The program will sometimes segfault

Expected outcome

The TextView should clear its contents including the button without segfaulting
