Can't Open File (PdfSharp.Pdf.IO.ObjectNotAvailableException)

[wessleym]

Thank you for PDFsharp!

I'm trying to read a file with PDFsharp 6.2.4. To me, the file does not seem corrupt since my PDF reader can open it. Upon calling PdfSharp.Pdf.IO.PdfReader.Open, I get the below exception. I'm including the file: CR1.pdf. Thank you for your help.

Exception:
Type: PdfSharp.Pdf.IO.ObjectNotAvailableException
Message:
Cannot retrieve stream length.
PDFsharp cannot read this PDF file. If you think your file is a valid PDF file please send it to us so that we can fix this bug in the PDF parser.

The error is caused by 12 unnecessary line feeds at the end of a stream before the token "endstream". While unusual, this is a bug in PDFsharp. It will be fixed in the next version.

Thank you for reporting the bug.

@StLange, thank you! My project currently runs files through PdfSharp, and if an ObjectNotAvailableException occurs, it runs it through PdfSharpCore as a backup. But I would rather just use PdfSharp. I intend to return here if it happens again. Is there a private place where I can post these files, or do I just need to include them in the GitHub issue like I did here?
