I experienced a similar problem with Skype. When a chat call comes for the first time (so that the chat window is open for the first time) my system does not respond for about 30 seconds. After that, all seems to go as desired.
Some info on my system: - P4 2400 - 1GB RAM - Kubuntu Edgy (but the same happened with Dapper) -- lockup of edgy and crash of X https://launchpad.net/bugs/71037 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
