Hi, you can see in the stack trace that the core issue is coming from the UglyToad library that is doing the PDF reading. This is the Nuget package dependency that UmbracoExamine.PDF uses to read PDFs https://github.com/UglyToad/PdfPig. You can file an issue there, or see if just upgrading to the latest supported version of their library fixes the issue. Looks like the lastest stable version of that lib is 0.1.8 https://www.nuget.org/packages/PdfPig/0.1.8

You haven't mentioned what version of UmbracoExamine.PDF you are using either?

@bergmania I think you can close this since this isn't related to Umbraco code.
