I quickly took a glance at what apt-get would try to remove if you removed singond0, and the seemingly likely candidate for getting the applet back is (and this is a wild guess, using just the name of the package as a guide): rtcom-accounts-ui So, perhaps someone with a missing IM applet can try Code: apt-get --reinstall install rtcom-accounts-ui And see how that goes?
apt-get --reinstall install rtcom-accounts-ui
