and this error exists on my system as well now (didn't a while back).
I attempted the workaround script provided by @njs and I can confirm it "solves" the issue.
I then undid the script work-around and installed "libnss3-dev" (which depends on "libnspr4-dev") per @kktkht and this ALSO solved the issue.
Personally, IMHO, the script workaround is a cleaner solution since nothing else requires additional packages...especially 'dev' packages when not developing.
I created a script called "zotero-evince" which contains:
#!/bin/sh unset LD_LIBRARY_PATH exec evince "$@"
Make sure you make it executable and then point Zotero's config to use this script as the custom PDF viewer (Preferences -> General -> Open PDFs Using...).
I'm still curious why that has helped. I can open evince without issue in Zotero on Ubuntu 19.10, and I can't find the string LD_LIBRARY_PATH anywhere in the Zotero source.
Upgrade Storage
Only applying the fix from njs fixed the issue for now.

I've also experienced this problem randomly off and on in the past.
I indeed solved my problem with:
sudo apt install libnss3-dev
Restart Zotero. Then everything works!
