> On the govdocs1 corpus, nearly 91% of xls exceptions have this stacktrace:
> {noformat}
> Caused by: java.io.IOException: Invalid header signature; read
> 0x0010000000060409, expected 0xE11AB1A1E011CFD0 - Your file appears not to be
> a valid OLE2 document at

> Excel is able to open the few files that I tried, and it looks like Excel
> thinks these are version 4.
> On the POI user list, [~gagravarr] identified this header as pre-OLE2 and
> asked that we add the mime to Tika so that we can handle appropriately. Test
> file soon to be attached.
