Conversion crashes on empty case with comment surrounded by curly braces

[knetworx]

I had a few case statements in my AS3 code that looked like this:

case "somecase":
	{
		//trace("my debug output");
	} // Fall through intentionally
case "someothercase":
	{
		//success = true;
		break;
	}

expected result

case "somecase", "someothercase":
	{
		//success = true;
		break;
	}

actual result
Conversion crashes - command line says the following:

Uncaught exception - Invalid field access : index

I can get the expected result if I change the original AS3 code to

case "updatedirect":
case "update":
	{
		//success = true;
		break;
	}
