Hello,

I have a large PDF file (almost 300 MB) containing thousands of audio files. It
opens fine with Evince, but with Okular, the software freezes, and I have to
manually terminate it without being able to view the file.

If I launch it from the terminal, after a few seconds, I get these messages
(and I don't have the courage to wait for it to finish...). By the way, « Trop
de fichiers ouverts » means "Too many files open".
