Try this (maybe make a backup of the file first):
journal.php - line 586 (for me anyway)

PHP Code:

    $journalinfo= $db->query_first("
        SELECT
        journals.journalname,journals.journalist_id,journals.journal_id,journals.journalviews,journals.journalist,journals.journal_totalrating AS totalrating,journals.journal_totalvotes AS totalvotes,journals.journaldate,
        journals.whocanview,journals.allowbuddies,journals.whovoted,journals.lastentry_date,journals.status,journals.journaldesc,commentcount,entrycount,journals.ipaddress,usertextfield.jbuddylist,journals.private 
        FROM " . TABLE_PREFIX . "journals AS journals 
        LEFT JOIN " . TABLE_PREFIX . "usertextfield AS usertextfield ON (usertextfield.userid=journals.journalist_id) 
        WHERE journals.journal_id=$j
              AND journals.active=1
    "); 


Replace with

PHP Code:

    $journalinfo= $db->query_first("
        SELECT
        journals.journalname,journals.journalist_id,journals.journal_id,journals.journalviews,journals.journalist,journals.journal_totalrating AS totalrating,journals.journal_totalvotes AS totalvotes,journals.journaldate,
        journals.whocanview,journals.allowbuddies,journals.whovoted,journals.lastentry_date,journals.status,journals.journaldesc,commentcount,entrycount,journals.ipaddress,usertextfield.jbuddylist,journals.private ,
        userfield.*
        FROM " . TABLE_PREFIX . "journals AS journals 
        LEFT JOIN " . TABLE_PREFIX . "usertextfield AS usertextfield ON (usertextfield.userid=journals.journalist_id) 
        LEFT JOIN " . TABLE_PREFIX . "userfield AS userfield ON (journals.journalist_id = userfield.userid)
        WHERE journals.journal_id=$j
              AND journals.active=1
    "); 


This will add the profile fields to the $journalinfo array, so replace $bbuserinfo[fieldx] in your template with $journalinfo[fieldx].
