HS no showing if multilanguage vocabulary is enabled

Hi Wim,

it looks like this issue http://drupal.org/node/221660 but in drupal 6.
HS works just fine if I have my vocabulary set to the first radio button:
Settings from here /admin/content/taxonomy/edit/vocabulary/1

Multilingual options
Translation mode:
 [] None. No multilingual options for this vocabulary.
 [] Localize terms. Terms are common for all languages, but their name and description may be localized.
 [] Per language terms. Different terms will be allowed for each language and they can be translated.
 [] Set language to vocabulary. The vocabulary will have a global language and it will only show up for pages in that language.

As I wanted to translate the term names, I just checked "Localize terms. Terms are...", and then, when I go to edit a node it just displays the list of terms in a select list, as if HS was disabled.

It might be that this bug is present in the drupal 6 version of HS?
I'm very ready to look for the bug (if any!).

Thanks!
