waiting

+1 on this. pdfminer struggles with a large amount of documents I'm testing with. pymupdf, on the other hand opens anything I throw at it flawlessly. ocr=true will flip to use pymupdf, but has additional logic that makes it useful to OCR.

seems to be pdfminer:
pdfminer/pdfminer.six#1004
NixOS/nixpkgs#339919

there's a fix now but you'll have to wait until it gets released, which could be a while.
