Error importing RTF

[Daniel]

Hello, I am not sure whether to post this in the RichTextEditor forum or the Telerik Document Processing forum as this problem exists in both import/export methods.

This is the code that triggers the error:

using Telerik.WinForms.Documents.FormatProviders.Rtf;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var rtf = @"{\rtf1\ansicpg1252{\fonttbl{\f0Arial ;}{\f1Tahoma ;}}{\colortbl;\red0\green0\blue0;}\sectd{\*\footer}{\*\header}\paperw12240\paperh15839\margl1439\margr1439\margt1439\margb1439\pgbrdropt40\pgbrdrt\pgbrdrb\pgbrdrl\pgbrdrr{{\trowd\trautofit\irow0\lastrow\clnowrap\cellx9360{\ql{\pard{\trowd\trautofit\trkeep\irow0\intbl\itap2{\ql{\pard{\trowd\trrh-1727\trkeep\irow0\lastrow\intbl\itap3{\ql{\plain\f0\fs20\cf1 Aaron Fitz Electrical, your invoice(s) are past due.

I get a NullReferenceException

I am pretty sure that this RTF is well-formatted; it opens correctly in Microsoft Word, and it came directly from an export of a Telerik Report.

Is there anything I can do to fix this?
