hi andrzej if you're using a free distribution of linux (not a commercial one), you can also get in touch with the packager and tell her that some of the templates are not free, and get all the templates to be removed from the package (they are lazy: it's all or nothing).
i just checked the licence of the ones coming from vectorportal.com and they can be freely used in commercial projects but cannot be redistributed. http://www.vectorportal.com/en/copyright/ if you're really mean, contact vectorportal.com and tell them that scribus is infringing on their copyright muahahaha and you will then have a your template directory cleaned up very soon :-) ciao a.l.e
