Comment (by sadrul):

 mlundblad: I believe it's important that if the client doesn't support
 custom smileys (e.g. an unpatched pidgin) then it will display the text
 for the received custom smiley, instead of completely removing it (which
 appears to be the current state, judging from the screenshot).
