Hi Sebastien.
Thank You for an answer. And I apologize for such a long time without my
answer. (An accident, nothing serious).
So Sebastien, please tell me, which informations exactly do you need?
I'm thinking about a `journalctl -b 0` command, of course. Is there
something specific, that you want or need to gather?
I'm asking, because there is not *any* informations about Evince or
loading backend for 'application/pdf' - for example - in system log
files, such as »/var/log/{syslog,kern.log}«, even right after trying to
open '.pdf' or 'djvu' files etc. (as you asked for it in your comment).
I mean nothing valuable, that can help to diagnose this problem.
Yes, there is the same problem with '.djvu' files - they cannot be
opened via Evince. Summarizing: I have problems not only with '.pdf',
but with '.djvu' files also. I have no idea what about other supported
file formats (please see 4. and Evince AppArmor profile), because I
can't test them, right now. And honestly, I don't know if I will be able
to do this. Sorry. (So, I updated the bug report and added this
information).
Sebastien, you also asked about the result of the `debsums(1)` for
'libevdocument3-4', right? I had to install `debsums` package first but
here it is:

As We can see, there are two 'FAILED' results. So the file's MD5 sum
does not match, right? What do you think about this? Is this a bug or
something on my side went wrong?
Sebastien, I apologize You once again, for such a long time without
answer. Best regards.
