Title:
Fixing bug #1795668 breaks thumbnail creation on 32-bit Ubuntu

Confirmed

Bug description:
Impact
======
Thumbnailing doesn't work on Ubuntu 18.04 LTS or 18.10 on 32-bit installs.
Test Case
=========
Install Ubuntu 18.10 32-bit
Install the update. Log out and log back in.
Download a picture from the internet.
Open your file browser to the directory that contains the picture. The file
should show a thumbnail preview.
Regression Potential
====================
This fix was cherry-picked to the stable gnome-3-30 branch.
It was additionally tested by Iain Lane on usrmerged and non-usrmerged
systems. (We don't support usrmerge for Ubuntu 18.04 LTS or 18.10.)
Other Info
==========
Triaged as Critical for 18.04 LTS since this was a regression introduced in
the security update that backported the bubblewrap hardening to the
gnome-desktop3 thumbnailer.
Original Bug Report
===================
Fixing bug #1795668 breaks thumbnail creation on 32-bit Ubuntu.
Looks like same issue in upstream -
https://bugzilla.redhat.com/show_bug.cgi?id=1651952
Cause - bubblewrap runs with --ro-bind /lib64 option, then fails.
Workaround - create empty /lib64 directory at root.
