[Mono-dev] Possible bug in Enumerable.cs?

[anidotnet]

I have the following function to remove a particular character from a string

public static string Remove(this string strA, char target)
{
	char[] charArr = strA.ToCharArray();
        var targetArr = new List<char>();	
	targetArr.AddRange(
                        charArr.Where(
                            character =>
                           
!character.ToString(CultureInfo.InvariantCulture).Equals(
                               
target.ToString(CultureInfo.InvariantCulture), 
				StringComparison.InvariantCultureIgnoreCase)));
	return new string(targetArr.ToArray());
}

using this function in .Net framework gives rise to

"Hello World".Remove('l')  ---> Heo Word

but Mono throws the following exception

System.InvalidProgramException: Invalid IL code in (wrapper delegate-invoke)
System.Func`2<char, bool>:invoke_bool__this___char (char): IL_004d:

Why? Is it a bug or something else?
