EPiServer 7.5

It seems that EPiServer is not correctly working with some cultures like Norwegian. To reproduce an issue, please add one of the following languages inside the "Manage Websites Language":

• norsk, nynorsk (Noreg) nn-NO
• norsk no
• norsk (bokmål) nb 
• norsk, bokmål (Norge) nb-NO

Then do the following steps:

• Create Start page
• Create Some page inside it
• Try to copy & paste

Or just use something like this: ServiceLocator.Current.GetInstance().GetDefault(createAssetFolder.ContentLink, (ILanguageSelector) new LanguageSelector(language.TwoLetterISOLanguageName));

Server Error in '/' Application.
