Translation off since updating to 2.0.4

Hi to all! I’ve just updated to version 2.0.4 from 2.0.1 and all the tags that were translated before now are not. I’ve downloaded different translation files but nothing is solved. The only things I’ve done for updating were:

– Download latest version (2.0.4)
– Go to http://myserver/wp-admin/upgrade.php
– Follow the instructions found in: “http://wordpress.org/support/topic/48398?replies=11” as I got “Fatal error: Only variables can be passed by reference in (…)/wp-includes/gettext.php on line 66” error:

**** I’ve found easy solution –

just edit includes/gettext.php
– find unpack(‘V’

change this
array_shift(unpack(‘V’, $this->STREAM->read(4)));
to
$tmp=unpack(‘V’, $this->STREAM->read(4));
return array_shift($tmp);

It worked on my blog.. ****

Could this cause the translation error?

If so, how can I solve the problem “Fatal error: Only variables can be passed by reference in (…)/wp-includes/gettext.php on line 66” without affecting the language translation?

Thanks in advanced.
