Comment:
Here are the specific points abou the new dialog that I see are issues:

1. Only the cancel button actually *looks* like a button
2. No other dialog on the desktop has two rows of icons (principle of least surprise)
3. The icons don't fit within the rest of the theme

If we revert, we should also consider removing the panel icon. Paul Sladen made a good comment about why we should here:

It should be noted that Fedora Core 4 has the sound icon in the upper
right.
