This is base library problem occurring on the first page - the second page works. I will open a bug in MuPDF's issue system.

I encountered the same on Friday with 1.24.1. Rolling back to 1.23.14 "fixed" it.
Interestingly enough, it was triggered on a .pdf with the same first page as @xiaominghero shared (attached).
(❗ note that we encountered this on different files, not just this one)
import fitz
doc = fitz.open("I_break_things.pdf")
doc
Interestingly enough, it was triggered on a .pdf with the same first page as @xiaominghero shared (attached).
It is this one page that causes the problem - not any other.
Hi @JorjMcKie ,
I still run into the same issues on 1.24.2 while testing on the file (the first page) that @jan-benisek submitted.
That is,
import fitz
fitz.open("I_break_things.pdf")[0].get_text()
hangs, while working fine on 1.23.14.
Sorry - my bad. The required / developed MuPDF fix is not contained in this version yet. I am re-opening the issue.
