Null reference exception opening doc with older file version

Null reference exception thrown when opening an old doc file. Example attached. 

As a workaround, the file can be opened in word and using the Doc compatibility mode converter and then this works, but since this file used to be readable with an older version of DocIO, it would be nice to still be handled.

Error information:

System.NullReferenceException

  HResult=0x80004003

  Message=Object reference not set to an instance of an object.

  Source=Syncfusion.DocIO.Base
