Comment 1 for bug 367176

Since kblogger is at this point very unstable and has not been updated in nearly a year, we have removed it from distribution for future versions of Kubuntu. Unfortunately this means that will no longer be able to provide bugfixes for this package. (Though since its development has been stalled for a year this was unlikely anyways.)

You may with to try "blogilo", KDE's blogging application for KDE 4.4. It will be available in Kubuntu 10.04 to be released this April.
