Yesterday I enabled the karmic-backports repository to install KDE SC 4.3.4. The upgrade went fine except the kde-l10n-hu package: it conflicted with the kde-i18n-hu package (it’s a known problem, there are some bugreport on Launchpad), this affects all kde-i18n-* package. So if you want to upgrade your KDE to 4.3.4 from karmic-backports, first remove the kde-i18n-* package. There’s another issue when I watch videos with VLC: in fullscreen mode the XVideo output doesn’t hide the panel. At this moment I can’t find a workaround for it, however I’m not a Kubuntu developer, I would be happy to fix the kde-i18n-* bugs. So let’s go to #kubuntu-devel!
