In addition, it appears that this has something to do with my existing config files in ~/.kde. Before the upgrade, I had konsole setup to emulate a vt420pc term type. I found out that if I remove the line in ~/.kde/share/apps/konsole/Shell.profile that says KeyBindings=vt420pc then konsole will start up. The problem with this is that my backspace and del keybindings are wrong. I want backspace to send <ctrl-H> and delete to send an <ASCII DEL>. vt420pc emulation used to do that.

In my mind there are 2 problems with this. The first is that previous working configurations should not cause konsole to crash. The 2nd is that I can no longer see how to configure konsole to use the keybindings I have been using for the last 15+ years. Is this documented somewhere? If it is, the location is non-obvious to me, as looking at the kde documentation and google have not revealed it.
