The on message receipt notification behavior in empathy is semi-broken. Just how broken depends on whether I have an open chat window with the sender.
If the chat window is open:
1. I get a little notification bubble in the top-right corner containing the name of the sender and the message.
2. The tiny triangle to the left of the empathy icon on the dock switches color from white to blue.
3. The status icon in the entry for the sender in the empathy contact list rapidly switches state back and forth.
Missing from all this is the message envelope indicator thing in the top panel. It no longer turns blue, and the name of the sender no longer appears as an entry in the indicator's menu.
If there was no chat window (or I've since closed it), all I get is #3 from the above list. This has caused me to miss a number of messages.
This is a regression: empathy was not broken like this in 12.10. It's happened to me with both of my Google accounts; I haven't tested any other accounts with it.
