Not a bug;
hauteboy will describe this better for you but basically it is a result of the way you do copy+paste; just ensure there are no unwanted carriage returns and/or line feeds and/or spaces at the end of the string that you paste into the edit box, and everything should be fine.
Edited to add: now, if the script did a little parsing of the string, to clean it up before processing, that probably would not hurt.
