Thanks for your bug report.

This output confuses me:
/usr/share/perl5/OpenOffice/OODoc/XPath.pm and
OpenOffice::OODoc::File are from libopenoffice-oodoc-perl but neither
unoconv (which seems to be a python program) nor libarchive-zip-perl
depend on it. And I see no mention of Archive::Zip anywhere.

And: I can't reproduce the bug.

After starting the listener in one terminal (unoconv -l), I converted
83 *.odt file in a row with:
% for o in *.odt ; do unoconv -f pdf -n  -T 60 -e PageRange=1-2 "$o"; done

There was no output, and in the end I had 83 PDFs.

Which program is using it?
Looks like there's something else involved, which might also use
OpenOffice::OODoc and cause the error output above.
 

OTOH, the line
| 	format error: CRC or size mismatch while skipping data descriptor at
is the same as the one mentioned at
https://github.com/redhotpenguin/perl-Archive-Zip/issues/11
which is supposed to be fixed in Archive::Zip 1.46, according to
https://metacpan.org/changes/distribution/Archive-Zip , so maybe
$unknown-program doesn't only use OpenOffice::OODoc but also
Archive::Zip?

https://rt.cpan.org/Public/Bug/Display.html?id=92205 also mentions
this issue.


(I just tried to update the package to 1.46-1 but there is a test
failure ...)
