Why does it crash? Can it be more than a crash? Does libpurple
created two '\n' users from that one changing nick to <br>, or does it
have the first one for some other purpose?

Josh is not reading his mails too often these days, but we can help you
with CVE assignment, if you as upstream are going to treat this as
security issue. CVE can be assigned before the issue is publicly
disclosed, so you can use it in e.g. new release announcements.
By "remote exploitability", do you mean whether it's more than a crash?
