Reopened Issue: There isn't a worksheet named '#REF' [8465]

I've attached a simple workbook that can't be opened. It works fine with OpenXML library directly (and incidentally with NPOI and EPPlus).The Exceptions is: There isn't a worksheet named '#REF'.Details:This file was fine when first created but I then added, then deleted, sheets from another workbook that was exhibiting this same problem.I found this entry in the forum which is identical:http://closedxml.codeplex.com/discussions/350351
