taxonomy_block URLS + pathauto

Hi, i've got a little problem with the taxonomy_blocks:

$content .= '<div class="more-link '. (substr(decbin($x), -1) ? 'flip' : 'flop') .'">'. l(t("more"), 'taxonomy/term/'. implode($tids, '+'), array("title" => t("View All."))) .'</div>';

this is suposed to show a "more" link at the right bottom of the block.

In mt site, for all taxonomy's, the URL is not the same as the one specified in the pathauto module.

example:
the link is:
"www.___.com/taxonomy/term/7+5+25+28+30+10+27+6+26+8"
when should be:
"www.___.com/news"

I don't know if i'ts only a problem with my site.

When i try to rewrite the url with the PATH module (manually) i can't because the URL "/news" is already used by the taxonomy "news".

¿How can i transform the link "more"?

thanks.
