Checking the condition of a string to be empty (Ie. "") causes MF to generate a segmentation fault. This is sometimes useful when you want to mark a String as NULL, empty, or uninitialised and you check it by seeing if it's empty or not. Since MF crashes when doing so, the users only recourse is to set a string to some unique identifier that means the same thing (Ie. "-1", "NULL", etc) and hope they never need a real string of that value.

This should be fixed by the same commit that fixed issue #5.
