In Freya it seems to look for these icons: emblem-ubuntuone-synchronized.svg, emblem-ubuntuone-unsynchronized.svg, emblem-ubuntuone-updating.svg in /usr/share/icons/hicolor/24x24/emblems. I didn't have these installed by default so had to grab them from various sites on the net. The icons for dropbox in /usr/share/nautilus-dropbox/emblems were not compatible as they were 64x64 png files instead of 24x24 svg files that seem to be required. I put the downloaded icons in /usr/share/icons/hicolor/24x24/emblems and they started working no problem.
