[Pharo-project] Bug in pharo image

Hi, I think I found bug in pharo image. I would post it in bug tracker but I don't know if it is not duplicate to this bug http://code.google.com/p/pharo/issues/detail?id=3349&can=1&q=ConnectionQueue.... If you create ConnectionQueue to listen to some port, send it message "getConnectionOrNil" and there IS connection, debuger pops out with "MessageNotUnderstood True>>isConnected". I searched through code and obviously it is problem in ConnectionQueue>>listenLoop, that sends bad message to socket (Socket>>waitForConnection:), that returns true or false, not connection itself. It is works in squeak image. Should I post it to bugtracker? Or am I wrong? And isn't it duplicate to that link? Thanks, Jan
