Jovie (KDE) forgets settings on startup or entering configuration window

[Surak]

In Kubuntu 12.04 (this bug comes from previous versions) when you restart the computer (or session) or when you right-click on Jovie's icon in the panel tray and access configurations and select the last tab ("Trabalhos" in Brazilian Portuguese, probably jobs or works in English) any previous change that you have made is forgotten. This is terribly annoying. Language defaults back to english, voice type goes back to male 1 and speed, pitch and volume defaults back to 0.

If it happened only when accessing the configuration, it would be acceptable, but configurations return back to default at every boot, too.

Thanks in advance.
