Since upgrading from 11.10 to 12.04, the microblogging and instant messaging entries have reappeared in the messaging menu. I put symlinks in ~/.config/indicators/messages/applications-blacklist to deactivate empathy evolution gwibber.indicator ubuntuone-control-panel, but this does not seem to have any effect now. How can I remove these entries? I would like to remove the status entries as well, and keep only Thunderbird information.
