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
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.
