Did you also used the "Kubuntu Backports PPA" as bug 199300 ? Thanks
I'm not so sure whether does this help, but in my case, I've removed .local and .config which is located in home directory(Additional, I've also removed all FILES in ~/.kde/cache-{systemname}/ and all FILES in ~/.kde/cache-{systemname}/kpc.) then re-login and that crash of kbuildsyscoca4 has gone.
