/!\ The category and template regexes below are required since Moin 1.9.1+ as system pages use them for page naming.

{{{#!highlight python numbers=off
    page_category_regex = ur'(?P<all>Categoria(?P<key>(?!Template)\S+))'
    page_template_regex = ur'(?P<all>TemplateDe(?P<key>\S+))'
    page_dict_regex = ur'(?P<all>Dic(?P<key>\S+))'
    page_group_regex = ur'(?P<all>Grupo(?P<key>\S+))'
}}}

Tested and working with MoinMoin 1.8.5:

{{{#!highlight python numbers=off
    language_default    = 'it'
    page_category_regex = ur'(?P<all>Categoria(?P<key>(?!Modello)\S+))'
    page_dict_regex     = ur'(?P<all>(?P<key>\S+)Dict)'
    page_group_regex    = ur'(?P<all>Gruppo(?P<key>\S+))'
    page_template_regex = ur'(?P<all>(?P<key>\S+)Modello)'
}}}

For Russian-only content wiki:

{{{#!highlight python numbers=off
    language_default    = 'ru'
    page_category_regex = ur'(?P<all>Категория(?P<key>\S+))'
    page_dict_regex     = ur'(?P<all>(?P<key>\S+)(Словарь|Dict))'
    page_group_regex    = ur'(?P<all>Группа(?P<key>\S+))'
    page_template_regex = ur'(?P<all>Шаблон(?P<key>\S+))'
}}}
For bilingual (Russian/English) wiki (recommended):

{{{#!highlight python numbers=off
    language_default    = 'ru'
    page_category_regex = ur'(?P<all>(Категория|Category)(?P<key>\S+))'
    page_dict_regex     = ur'(?P<all>(?P<key>\S+)(Словарь|Dict))'
    page_group_regex    = ur'(?P<all>((?!.*Group)(?P<ru>Группа))?(?P<key>\S+)(?(ru)|Group))'
    page_template_regex = ur'(?P<all>((?!.*Template)(?P<ru>Шаблон))?(?P<key>\S+)(?(ru)|Template))'
}}}

{{{#!highlight python numbers=off
    language_default    = 'de'
    page_category_regex = ur'(?P<all>Kategorie(?P<key>\S+))'
    page_group_regex    = ur'(?P<all>Gruppe(?P<key>\S+))'
    page_template_regex = ur'(?P<all>(?P<key>\S+)Vorlage)'
}}}
I like this

{{{#!highlight python numbers=off
    page_category_regex = ur'(?P<all>Kategorie(?P<key>(?!Vorlage)\S+))'
    page_group_regex    = ur'(?P<all>(?P<key>\S+)Gruppe)'
    page_template_regex = ur'(?P<all>(?P<key>\S+)Vorlage)'
