Errors
If the template is used on invalid page, an error message is generated and the page is categorised in:
 * Category: (population: )

Errors include:


 * The page is not in the category namespace
 * The page's title does not take the form "XXth century in nationality television"
 * The value of "nationality" does not correspond to a country name.  The conversion is made using GetCountryNameFromAdjective, so the problem may be a glitch in that template's lookup table
