This bug went away after the latest sudo aptitude full-upgrade. Or else, it went away when I finally stopped using gnome-panel for the notification area applet.
I kept using a gnome-panel for notification area for gnote and checkgmail until I finally discovered how to make them show up in the indicator applet (i.e. Unity Panel Systray):
1. gsettings get com.canonical.Unity.Panel systray-whitelist
to find out what apps are already allowed in the indicator applet, then
2. gsettings set com.canonical.Unity.Panel systray-whitelist "COPY AND PASTE THE OUTPUT FROM 1. THEN ADD NEW APPS TO IT"
So, to get gnote and checkgmail to show up in systray, the command I used for step 2. was
gsettings set com.canonical.Unity.Panel systray-whitelist ['JavaEmbeddedFrame', 'Mumble', 'Wine', 'Skype', 'Checkgmail', 'Gnote']
