Web addresses not handled right...

I have a database with members website addresses as one of the fields.

When joodb displays it, it displays it as it shows in the database. But, when you roll over it with the mouse, the link it shows is "http//www.something.com" without the ":" (colon). This causes the link to fail because it's not properly formed.
So, database has:
www.something.com
joodb created URL shows:

http//www.something.com

Could this really have been overlooked for this long?

There is a problem with the php code. I got it the other way:
DB entry was www.example.com
When a user then clicks on it the browser it comes up with an error, cause the link will be:
http://http://www.example.com
Also when you hover over the link it shows the double http://http://

Update the code in helpers/joodb.php

from:
if ($params->get('link_urls')) {
// try to detect and link urls and emails
if (preg_match('/^[^@]+@[a-zA-Z0-9._-]+\.[a-zA-Z]+$/', $field)) {
$field= JHtml::_('email.cloak', $field);
} else if (strtolower(substr($field,0,4))=="www.") {
$field= '<a href="http://'.$field.'" target"_blank">'.$field.'';
} else if (strtolower(substr($field,0,4))=="http") {
$field= '<a href="http://'.$field.'" target"_blank">'.$field.'';

to

if ($params->get('link_urls')) {
// try to detect and link urls and emails
if (preg_match('/^[^@]+@[a-zA-Z0-9._-]+\.[a-zA-Z]+$/', $field)) {
$field= JHtml::_('email.cloak', $field);
} else if (strtolower(substr($field,0,4))=="www.") {
$field= '<a href="http://'.$field.'" target"_blank">'.$field.'';
} else if (strtolower(substr($field,0,4))=="http") {
$field= '<a href="'.$field.'" target"_blank">'.$field.'</a>';

And it should work
