In one of my previous posts , i talked of how to solve the SSL/TLS problem with psi for Google Talk .
Here is what the wiki for Psi has to say.
** Linux users must ensure that they have the QCA-TLS package installed first. SSL encryption will not work otherwise and you will not be able to connect to your Google Talk account.
And about the stupid help at Google's website(ya, they do have a section aptly titled "Why are these instructions different from Google's instructions?"
The answer: Google uses psi 0.9.3 for their instructions. The method described here is for psi 0.10.
As of writing the post, psi 0.10 is the latest release and 0.11 is put up for testing.
A must for all psi users: Visit Psi's Website and the psi Wiki
