> I've discovered that a small number of excel files (and possibly others, though I haven't noticed any) will cause com.sun.org.apache.xml.internal.serializer.ToStream.writeAttrString to blow up with a NPE. The text being passed through from the Excel parser looks fine though.

> Looking at the excel parser code, it seems that we're not doing anything wrong, so I think the issue is with the SAX stuff used by the CLI
