Unhandled Exception when opening epub file #85

Epub Metadata Editor works great but i had an issue with one epub file. When I try to open it using EPUP Metadata Editor Version 1.9.6 The below Error is shown.

When I loaded the epub into Calibre I was able to see and edit the Metadata in Calibre. When I imported the file in Calibre and exprted it from Calibre, I was able to open it using Epub Metadata Editor.

System.ArgumentException: The argument start must be bigger than 0 (null).

Sounds like there was an issue with the EPUB. If you can attach the original to a comment here on Github (just change .epub to .jpg and then attach the file as an image) I might be able to incorporate the required error checking. Otherwise, your solution of going through Calibre will have to do!

The .epub in question is a book I bought. I don't want to share it publicly. Since it worked when going through Calibre I'm ok with it. This is the eBook in question: https://www.thalia.de/shop/home/artikeldetails/A1063544345
