I have no idea what this is, can anyone help?

The problem is that all of the 'assistive technology' stuff like at-spi2-registryd and at-spi-core cannot be removed properly, despite being disabled, without pulling out a whole load of programs. The best way i've found is to stop it from running with:
sudo mv /usr/lib/at-spi2-core/at-spi2-registryd /usr/lib/at-spi2-core/at-spi2-registryd.oldand
sudo mv /usr/lib/at-spi2-core/at-spi-bus-launcher /usr/lib/at-spi2-core/at-spi-bus-launcher.old
