adept runs as root, and therefore it uses the settings in /root/.kde/share/config/kioslaverc when it tries to fetch any file from http://changelogs.ubuntu.com/ (upgradewizard.cpp:161). My root's kioslaverc had an invalid proxy, so no file was being retrieved which eventually was leading to the crash I was experiencing. Applying the attached patch helped me determine the problem.
I had the same behaviour (crash after pressing "next") while trying to update to hardy, following the instructions in https:/ /help.ubuntu. com/community/ HardyUpgrades/ Kubuntu.
This time I found the problem, though. :)

As a side note, the file http:// changelogs. ubuntu. com/meta- release- proposed does not currently contain an entry for hardy, only meta-release- development does.
