you might want to try a new username. I'm on my second one too. I added Skype on my first one and it crashed every single time. So I just started a new user name and all seems fine now.
that did the trick, still, I found a bug, it only crashes when trying to connect to the icq network, I deleted the icq account and since then it hasn't crashed even once.
Another bug seems to be that when being logged into skype on let's say you laptop, you can't receive a skype call. After I quit skype on my macbook it worked.
Still needs a lot of work, but for a start, not too bad.
