This might not be specific to empathy: I see the same issue in xchat and weechat. There's something else affecting it, though: from home on the wired net, xchat always reconnects right away when I resume from suspend, but when I'm traveling and using wifi, neither xchat nor weechat will reconnect automatically, and I have to go through all the server tabs running manual reconnects. I haven't been able to figure out what the difference is. Happens in 12.04 but it's been true for some time now, definitely not new with Pangolin.
