Zotero is a bibliography tool (https://www.zotero.org/). When I double click on a pdf in it, it opens the pdf file using the default system tool, here evince, and triggers that evince error.
Here is the tail of journalctl -b 0 output with the relevant lines: mars 27 11:53:08 darwin audit[52507]: AVC apparmor="DENIED" operation="file_mmap" profile="/usr/bin/evince" name="/home/nicolas/Zotero_linux-x86_64/libnss3.so" pid=52507 comm="EvJobScheduler" requested_mask="m" denied_mask="m" fsuid=1000 ouid=1000 mars 27 11:53:08 darwin kernel: audit: type=1400 audit(1585306388.116:3096): apparmor="DENIED" operation="file_mmap" profile="/usr/bin/evince" name="/home/nicolas/Zotero_linux-x86_64/libnss3.so" pid=52507 comm="EvJobScheduler" requested_mask="m" denied_mask="m" fsuid=1000 ouid=1000 mars 27 11:53:08 darwin kernel: audit: type=1400 audit(1585306388.116:3097): apparmor="DENIED" operation="file_mmap" profile="/usr/bin/evince" name="/home/nicolas/Zotero_linux-x86_64/libnss3.so" pid=52507 comm="EvJobScheduler" requested_mask="m" denied_mask="m" fsuid=1000 ouid=1000 mars 27 11:53:08 darwin audit[52507]: AVC apparmor="DENIED" operation="file_mmap" profile="/usr/bin/evince" name="/home/nicolas/Zotero_linux-x86_64/libnss3.so" pid=52507 comm="EvJobScheduler" requested_mask="m" denied_mask="m" fsuid=1000 ouid=1000 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1869159 Title: Opening a pdf from Zotero in evince, I got "failed to load backend for 'application/pdf': libnss3.so: failed to load shared object mapping segment Status in evince package in Ubuntu: Incomplete Bug description: Opening a pdf file from Zotero in evince, I got "failed to load backend for 'application/pdf': libnss3.so: failed to load shared object mapping segment" and the file won't open.
