This reverts commit 72037d6143.
Until some of the XHR notice related bugs are sorted out in Opera and
Chromium, reverting back to the previous version. It throws slightly
less errors. XHR file attachments is still a bit problematic in
Opera 10.10/Ubuntu, Opera 10.10/Windows, and Chrome 4/Ubuntu. But this
revert will at least allow regular XHR notices to work okay in Opera
and Chromium.
Standards suck!
