Hello,

When executing this piece of code:

merger = PdfFileMerger(strict=False)
merger.append(some_file)

with BytesIO() as output_io:
    merger.write(output_io)

I get the following error: Unable to find 'endstream' marker after stream at byte 0x1047a.

I saw the issue #167 which seemed similar, but the cause is not the same, since the file I am trying to merge has a size of only 70kB. Any help regarding this issue?

PS: I am using version 1.25.1. I tried to upgrade to 1.26.0, I experienced the same issue.
