Comment 2 for bug 336203

Errata added for beta:

 * In some cases, the "Prepare Disk Space" screen in the desktop installer displays obviously incorrect partition sizes in its graphical disk previews. This is only an error in the preview and does not reflect a problem with the partitioning changes that will actually be applied. Bug:336203

I'm leaving this bug at "Fix Committed" since bug 289663 has not been fixed yet and so there's a possibility that we might have to carry this over to the final release notes.
