PHP Fatal error: Cannot redeclare quoted_printable_encode()

[rsc]

With PHP 5.3 RC2, I get the following:

PHP Fatal error:  Cannot redeclare quoted_printable_encode() in /data/var/www/roundcubemail/program/include/rcube_imap.php on line 3134

Workaround is putting a function_exists() around the function definition itself (the function anyway seems to be used nowhere?):

if(!function_exists('quoted_printable_encode'))
{
  function quoted_printable_encode($input, $line_max=76, $space_conv=false)
  {
    /* ... */
  }
}

Function removed in [a1fc8d25].
