[5.0 Beta] - error on linux related to libnss3.so

Tip: For anyone using Linux, if you get the error "Failed to load backend for 'application/pdf': libnss3.so: failed to map segment from shared object" when trying to open a PDF attachment, then it is easy to fix: Just re-download zotero.

This has happened to me three times already, and re-downloading zotero has fixed it for me every time. (Just re-download the standalone application folder, you don't need to touch the settings or storage.)

I guess something about libnss3.so gets messed up by the auto-updater sometimes.
  • There haven't been any other reports of this, but if you're seeing this repeatedly, if you could keep an eye on what version you're on and what you're updating to, we can try to replicate it with a specific version upgrade.
  • This happens to me pretty much continuously with v4.0.29.10 on Lubuntu 17.04. I'll try reinstalling now.
  • Reinstalling did not change things. I am also getting the message:

    Failed to load backend for 'application/pdf': libnss3.so: failed to map segment from shared object
