GTalk and crashing IM clients

I am using KDE 4.1.1. I configured my GTalk account in Kopete and tried to go online. I’ve seen my roster to appear for a second, then Kopete crashed.

I also installed latest version of Psi (from Yast). I can log in to my GTalk account via Psi, and chat, but eventually Psi crashes too.

Is it usual for current state of these clients?
