I'm parsing Excel file from EUSES data set. When get formula of name 'Database' with range ='file:///HEPPC3/gt$/Teaching/Syn/[physyn.xls]#REF'!$AK$70:$AL$70

It throw null pointer exception:
for(Name rangedName : wb.getAllNames())
  if (!rangedName.isFunctionName()) {
    xlWorkbook.addNamedRange(rangedName.getNameName(), rangedName.getRefersToFormula());

Exception in thread "main" java.lang.NullPointerException
	at org.apache.poi.ss.formula.ptg.ExternSheetNameResolver.prependSheetName(ExternSheetNameResolver.java:40)
	at org.apache.poi.ss.formula.ptg.Area3DPtg.toFormulaString(Area3DPtg.java:104)
	at org.apache.poi.ss.formula.FormulaRenderer.toFormulaString(FormulaRenderer.java:91)

	at org.apache.poi.hssf.usermodel.HSSFName.getRefersToFormula(HSSFName.java:204)

Sheetname is null. I guess sheet name is #REF error in Excel. Should it return #REF or the index of sheet?

Attached file is test file to replicate the issues.
