my report was not about DCC sending or receiving, but about the dialog window buttons not responding the way they should =)
Typical application behaviour is when the focus in on a button component (by tabbing to it for instance), hitting "enter" will trigger whichever event is bound to the button. In this particular dialog, that behaviour does not exist, hence the bug report rather than the "help help I do not know IRC commands how do I send/receive DCC without a mouse" kind of message you'd find in a general help forum =)
