The problem occurred during the upgrading process from Kubuntu 8.10 to 9.04. This has something to do with "kaddressbook," files, and I understand the problem I encountered is not critical and the upgrade from Kubuntu 8.10 to Kubuntu 9.04 will continue. I did not experience this problem last night, while upgrading Kubuntu on a different laptop.

I could not find the /var/log/dist-upgrade/ folder, presumably because the upgrading process has not been completed yet. I am attaching /var/log/syslog instead, although I am not sure if this is relevant.
