The handler should be:
static void handler(GtkWidget *widget, GtkTextView *tview)
{
GtkTextBuffer *buffer = NULL;
GtkTextIter iterator;
buffer = gtk_text_view_get_buffer(tview);
g_assert(buffer != NULL); <<< assert that it is not null
gtk_text_buffer_get_end_iter(buffer, &iterator); <<< pass an allocated
iterator
gtk_text_buffer_insert(buffer, &iterator, "Info message", -1);
}
