Here is another workaround solution that can be leveraged until KDE gets this fixed (https://bugs.kde.org/show_bug.cgi?id=162485), or maybe if they fix it judging by how long the bug report has been open.

My new SSL cert for uses a chained certificate, and was loading with an authenticity check warning because "Entrust.net Certification Authority (2048)" was not included in KDE's ca-bundle.crt. And to add insult to injury KDE no longer has a GUI to import CA Certificates.

Simply appending the Entrust.net_Premium_2048_Secure_Server_CA.crt (already installed from the "ca-certificates" package) to KDE's ca-bundle.crt then restarting KDE fixed this issue for both konqueror and kmail.

$ sudo cp -p /usr/share/kde4/apps/kssl/ca-bundle.crt /usr/share/kde4/apps/kssl/ca-bundle.crt.orig
$ sudo cat /usr/share/ca-certificates/mozilla/Entrust.net_Premium_2048_Secure_Server_CA.crt >> /usr/share/kde4/apps/kssl/ca-bundle.crt
Restart KDE
