When a content is created, it's assigned a default title, which value is "New Content Type", "New" being internationalized, i.e. "New article" or "New photo gallery".
In english, no problem.
When in french (and without a doubt in many other languages), it becomes "Nouveau actualité", "Nouveau galerie multimédia", "Nouveau offre d'emploi", and so on, which is terrible.
The content type XML definition should include an internationalizable string specifying the default title, like:

<cms:content-type>
    <cms:label i18n="true">CONTENT_TYPE_LABEL</cms:label>
    <cms:description i18n="true">CONTENT_TYPE_DESCRIPTION</cms:description>
    <cms:default-title i18n="true">CONTENT_TYPE_DEFAULT_TITLE</cms:description>
    ...
