pdfminer.six: AttributeError: 'PDFStream' object has no attribute 'replace'

Hello everybody,

At the moment I’m parsing tons of PDFs, but pdfminer.six fails on one of them. Any suggestions? I can open the PDF, but maybe pdfminer.six can’t handle it properly. All the other PDFs origin from the same author/organization…
