  Log Message:
  -----------
  new fix for parallel tab crash: NULL the pointer on destruction.

tried g_free(html_parallel_dialog) but that causes immediate crash in
free().  so we just NULL it out because apparently it's already freed by
then.

this seems to solve the problem since the pointer is NULL so the test in
main_update_parallel_page_detached() for "!widgets.html_parallel_dialog"
will correctly stop the failure.
