Never seen this before, I even do not know what at-spi is.
Same with okular.
"at-spi" is "Assistive Technology Service Provider Interface":

The error suggests you're trying to run evince and okular as root,
in a GUI/desktop session running as a non-root user, with the
latter being configured (perhaps by default) to support at-spi
services.
