It seems kubuntu 12 doesn't come with GTK 2.0 libraries by default (I think Ubuntu 12 does).
I'm no Linux expert myself but I think this can simply be solved by installing the GTK 2.0 package ("apt-get install libgtk2.0-0").
Although you might want to consult some other (forum) users first, I don't want you to mess up your kubuntu install.
