Subject: libspectre1: evince hangs with PS files, is there a need to rebuild it?

Date: Sat, 21 Nov 2020 14:27:51 +0100

Package: libspectre1
Version: 0.2.9-1
Severity: important

Dear Maintainer,

I am facing the exact situation reported here with evince:
https://bbs.archlinux.org/viewtopic.php?id=259223
and their solution was:
https://github.com/archlinux/svntogit-
packages/commits/packages/libspectre/trunk

Maybe libspectre should be rebuilt using 9.53.3~dfsg-5. No?

Thanks,
Patrice

And I confirm that rebuilding it targeting unstable distribution solved this.

I can confirm rebuild the library solves the problem on my system:

apt source libspectre1
sudo apt build-dep libspectre1
cd libspectre-0.2.9/
debuild -us -uc

This was fixed in Ghostscript since release 9.53.3~dfsg-6 - I just 
forgot to mention it in changelog (that will be corrected in next 
release).
