Displaying a UTF-8 file in a text view

Dear GTK+ users,

I am trying to display a UTF-8 file in a very simple GTK+ application using a
text view. Now, am sure that other things with my setup are fine, since gedit
displays the file with no problems. However, my application gives the following
error:

(llf_utf:8373): Gtk-CRITICAL **: gtk_text_buffer_emit_insert: assertion
`g_utf8_validate (text, len, NULL)' failed

The relevant part of the code is:
<code>
                gchar *buf, *actualText;                                       

                gsize n_read, n_written;                                       

                GtkTextBuffer *textBuffer = NULL;                              

                gsize n;                                                       

                g_file_get_contents(filename, &buf, &n, NULL);                 

                actualText = g_convert((const gchar *)buf, (gssize) n,         

                                       "UTF-8",                                

                                       "ISO8859-1",                            

                                       &n_read,                                

                                       &n_written,                             

                                       NULL);                                  

                textBuffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(textarea));

                gtk_text_buffer_set_text(GTK_TEXT_BUFFER(textBuffer),
actualText, n);
</code>

What could the mistake be? How do I read the UTF-8 file?

Thanks.

Kumar
