Server name is rejected for group chat bookmarks
I have a jabber account on a server whose hostname contains a "-". For some reason, when I want to add a group chat bookmark for that server, Gajim complains as soon as I hit the "-" key that I added an invalid character. Obviously, "-" is a valid character for the server of a group chat. Also, I was able to circumvent this check with the clipboard... (which is actually good, everything else would have been even more frustrating ;-)
Since nowadays, domain names can contain almost everything, I wonder what the purpose of that check is. The servername was accepted just fine as server for a new XMPP account, so it seems that the set of valid characters is replicated (inconsistently) over several locations?
