This message appeared in the log when an editor or admin tried to upload a PDF file. The upload in the backend worked and displaying the file works too. It's just weird that there is a warning/error.

I've seen this log numerous time but cannot understand which PDF causes that. Can you possibly attach a PDF leading to this message for further investigation?

OK, found a sample PDF and I can reproduce this problem: Sample.pdf

The corresponding chunk is:
