 Just a small bug:
  I found out that whenever you want to add a buddy on a ICQ account and
 have an accidential CRLF character at the end of it, the buddy can't be
 added.
 For example when you copy it off from a mail or web page it might be
 included by accident..

 Of course that's obvious that this "number" does not exists, but on the
 Windows platform you don't see the CRLF character like you do on linux.
 So you get stuck with the message
 "Couldn't add Buddy [the entered number+(invisible)CRLF]
  because the user name is wrong[...]"

 All invalid characters should be excluded from being added to the text
 field, especially when pasting something into it.
