Ubuntu MATE 16.04 restart/shut-down halts due to a not responding program. How to stop it?

Question

On my Ubuntu MATE 16.04, whenever I press shutdown, restart button, I get a message that at-spi-registryd.desktop program is not responding and I either need to wait for the program to finish or I could reboot/shutdown anyway (warns me that I may lose work). Why does this happen? How can I make the shutdown/restart process smoother ie. not see that message and restart/shutdown the normal way?

Solution

This seems to be a regression of this bug:

https://bugs.launchpad.net/ubuntu/+source/unity/+bug/729827

So, the workaround (provided you dont need assistive technologies) would be:

sudo mv /usr/lib/at-spi2-core/at-spi2-registryd /usr/lib/at-spi2-core/at-spi2-registryd.old

This renames the file for at-spi2-registry so that the system won't run it, but maybe you also want to reopen it on launchpad.

No, the only downside is that some "Assistive technology" apps (such as screen reader or on-screen keyboard) may not work correctly.
