Why not just edit Konsole's shortcuts to remove those keys? Konsole uses them for Go To Next/Previous Session.
These keys are unassigned in my Konsole configuration.
It turns out that XFree 4.x.x configuration is compiled into Konsole, but there is a template that corresponds to that configuration. That template is located in a file README.default.Keytab (due to capital K in Keytab my previous searches did not find it). Problem solved.
As for Ctrl+Up/Down for tab switching to me this is counter-intuitive. Tabs are displayed horizontally. Using keys for vertical movement to switch between them does not make much sense to me.
