While the rhythmbox packages with my scrobbler plug-in for Ubuntu Natty are building, here’s a short tip on how to get the last.fm client to show up in the system tray with Ubuntu Unity.

Run the following command in a terminal:

$ gsettings set com.canonical.Unity.Panel systray-whitelist \
    "$(gsettings get com.canonical.Unity.Panel systray-whitelist | \
       sed -e "s:\[:\['Last.fm' ,:")"

After logging out and back in, the last.fm client will show up in the systray again.
