Timevault doesn't play nice with Assistive Technology Enabled

When I have the "Assistive Technologies" enabled, I get an error when I login that the AT daemon couldn't start. This did not happen before Timevault. Also, when AT is enabled, the right click>Properties>Timevault tab does not show up in Nautilus, nor is there a Timevault button on the Main Toolbar. When I disable AT and login again, I do not get any error messages, and Timevault works flawlessly.

Looks nice, though, should be one of those "killer apps" that draws people to Ubuntu/Linux.
