Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. But don't worry! This issue is being tracked by the KDE developers at: https://bugs.kde.org/show_bug.cgi?id=228138
Once fixed in KDE, it will be included in Kubuntu once the KDE version the fix is in in reaches Kubuntu.

Thanks!

Reopening, since this report has garnered enough duplicates that it makes sense to track this, so that once a fix is made we can get it into Kubuntu 10.04, should the fix come after the final release.
