I have commented that line out now, but still no use.

In that case, I then set n to strlen(actualText), which should give me the right
value, as strlen checks for '\0'. But now, I get this:

(llf_utf:21130): Gtk-CRITICAL **: gtk_text_buffer_emit_insert: assertion
`g_utf8_validate (text, len, NULL)' failed
