I have configured Empathy with Facebook and Gmail just after installing Ubuntu 12.04. It worked flawlessly for few days and one fine day it crashed. After that when ever I am opening Empathy it is failing to connect to Gmail and Facebook ( I have not checked any other IM services).
After the crash I removed my account configurations and added once again but still facing the same issue.
Any pointer to fix issue is appreciable.

The reasoning is you're trying to use your log in e-mail address. It requires you to use your assigned name. The quickest way to find this information out is to login to Facebook via a web browser and check out your own profile. It should the web url as facebook . com / YOURNAMEHERE.
Use that given name and your password you used to log in and it should work.
