Ok, as far as KDE goes, the fix is to remove empathy. For some reason, when empathy was installed, the KDE Telepathy stuff was using empathy to authenticate, and it was failing. The Gtk error box and non-KDE desktop notification should have tipped me off sooner, but it wasn't until I brought up the KWin Special Application Settings for the Gtk "self- signed certificate" error box and saw that it was from the empathy process that I made the connection.
After removing empathy, when I tried to connect to GTalk, I got a kdewallet prompt, clicked Allow Always, and now it works fine. I don't know why KDE was using empathy when it didn't need to. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/828756 Title: getting "connection is untrusted" warnings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/828756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
