SEGFAULT in options dialog and FIX

[Torsten Uhlmann]

I did this to get rid of the segfault when opening the options dialog:

old code:
	QString *str = (QString*) m_set_modify_line->text();
  if (!str->isEmpty()) {
    text+=" -W";
    text+= m_set_modify_line->text();
  }

	str = (QString*) m_optional_line->text();
  if (!str->isEmpty()) {
    text+=" ";
    text+= m_optional_line->text();
  }

new code:
	QString *str = new QString;
	str->setStr(m_set_modify_line->text());
  if (!str->isEmpty()) {
    text+=" -W";
    text+= m_set_modify_line->text();
  }

	str->setStr(m_optional_line->text());
  if (!str->isEmpty()) {
    text+=" ";
    text+= m_optional_line->text();
  }
