I dont know why dislike was on version upgrade answer, but realy look -> document created in case of

worker.parseXHtml(writer, document, new StringReader("<p>helloworld</p>"));

with 2 libraries

itextsharp.xmlworker
iTextSharp

In this case I have firlst library very old and same error. So I could suggest if some one will face with the error in the future to compare both version of app. Currently work

iTextSharp 5 5 13 4
itextsharp.xmlworker 5 5 13 4

document.add(new Chunk("")); worked for me after document.open(); when the data is not there in the report text.

I know it's a bit late to this answer, but in my case just upgraded iTextSharp to v. 5.5 from 5.0 and started to work correctly.

Other answers are good. This is an alternative.

In general, to prevent this error which often occurs when the document contains no meaningful data for content, even despite document.open() and document.newPage() having been called, and even after stamping other pages into that document, you can add an empty chunk when the document is opened to ensure the library never considers it empty. e.g. 

document.open(); 
document.add(new Chunk("")); // << this will do the trick.

XMLWorkerHelper.parseXHtml() expects (X)HTML or (X)HTML snippets. Try this:

worker.parseXHtml(writer, document, new StringReader("<p>helloworld</p>"));

Try to new a page just like document.newPage() before you write something to document, hope that helps.
