problem with memory leaks

[morph_in <atandon_b03 iiita ac in>]

Hi,
   I am a newbie to GTK programming and cannot work out a simple problem ,so
pls can some one inform abt the problem

GtkTextBuffer *tbuffer;
    GtkTextIter start;
	GtkTextIter end;
	GtkWidget * textv = lookup_widget(GTK_WIDGET(menuitem), "textview1");
	tbuffer =gtk_text_view_get_buffer(textv);
	FILE *infile;
    infile = fopen("/root/Desktop/a.s", "r");
     if (infile)
      {
        char buffer[1024];
        int nchars;
        gchar *utf8;
        while (1)
          {
            nchars = fread(buffer, 1, 1024, infile);
            utf8 = g_locale_to_utf8(buffer, nchars, NULL, NULL, NULL);
           if (!utf8)
              { return;
             }
            gtk_text_buffer_get_end_iter(tbuffer, &end);
            gtk_text_buffer_insert(tbuffer, &end, utf8, strlen(utf8));

            if (nchars < 1024)
                break;
          }
        fclose (infile);
		  free(utf8);
      }
    gtk_text_view_set_buffer(GTK_TEXT_VIEW(textv), tbuffer);
		
//g_free(tbuffer);                         //freeing any of them produces
segmentation fault 
	 //g_free(textv);                   //and if i donot free them then i get a
15Kb leak 
	
So basically what am i doing wrong and what is the correct way to free the
memory allocated .Hoping for a response   
                Thx
Regards
morph_in
