Certain accept headers crash restfulie

[dotnetchris]

Accept: text/html,application/xhtml+xml,application/xml;image/png,image/jpeg,image/;q=0.9,/*;q=0.8

This will crash

AcceptHeaderToMediaType private FormatPlusQualifier ParseFormat(string type)

 if (ContainsQualifier(type))
            {
                var typeInfo = type.Split(';');
                format = typeInfo[0].Trim();
                qualifier = Convert.ToDouble(typeInfo[1].Split('=')[1], new CultureInfo("en-US"));
            }

This gets an instance of "application/xml;image/png" which it then splits at the ; and then tries to resplit on =, however since there is no = at all, typeInfo[1] is out of bounds of the array.

System.IndexOutOfRangeExceptionIndex was outside the bounds of the array.

Any input on this? I don't really understand content negotiation to resolve this properly as opposed to resolving this to just not throw an error
