I see this once in a while:

Looking at LdapVCardProvider.java, it does this:
// Un-escape username.
username = JID.unescapeNode(username);
Map<String, String> map = getLdapAttributes(username);
Log.debug("LdapVCardProvider: Getting mapped vcard for " + username);
Element vcard = new VCard(template).getVCard(map);
Maybe if map is null (is it null if user doesn’t exist?), loadVCard should be returning null before it calls getVCard?
