Status changed to 'Confirmed' because the bug affects multiple users.

It didn't make my machine unusable but at-spi2-registryd consumed a CPU core for quite a while until I killed it.

[Luke Yelavich (themuso)]

is this still a problem for people with all updates installed, and screen reader turned off? Does this problem ocur all the time, or in a specific application?

[Drew Snellgrove (forkinme-deactivatedaccount)]

This was with all updates installed and the screen reader has never been turned on. I hadn't seen the issue previously (I've been on 12.10 for about a week) and didn't see it today after shutting down overnight.
