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 Desktop Packages, which is subscribed to empathy in Ubuntu. https://bugs.launchpad.net/bugs/828756 Title: getting "connection is untrusted" warnings Status in “ca-certificates-java” package in Ubuntu: Confirmed Status in “empathy” package in Ubuntu: Incomplete Status in “icedtea-web” package in Ubuntu: Confirmed Status in “p11-kit” package in Ubuntu: Fix Released Status in “p11-kit” source package in Oneiric: Fix Released Status in “telepathy-gabble” package in Debian: Incomplete Bug description: Since updating to Oneiric, empathy is giving me "connection is untrusted" warning dialogs.
