--- Comment #7 from [email protected] --- I was able to open the test.pdf file originally reported (using LibreOffice 7.2.0.4 on Mac). There is an error message "This document has an invalid signature." and Show Signatures shows four signatures that can't be found. I am here because I got the same message with one of my own PDF files. I don't want to upload it here because it is 44MB and I need to redact it before sharing. It am less concerned that LibreOffice can't open it than I am that the message is "General Error. General input/output error." and I cannot figure out how to get more details. Nothing is written to stderr/stdout. There is nothing in the system log. -- You are receiving this mail because: You are the assignee for the bug.
