Tomboy not working correctly through proxy

[nick]

The ability to sync the Tomboy notes with my Ubuntu One account through a proxy is not working with the latest release of Ubuntu 11.10 beta 1.

This is a major issue, as this is used for work based requirements, and was working perfectly with 11.04.
