Table term_node is not populated with terms.

Nobody?

With every new import, the module creates duplicates of existing terms in the taxonomy.
When I set the Freetagging settings: in the cck taxonomie field to :"Deny any new terms", no terms are extracted from the image..
Please help
ps the option "Save values additionally to the core taxonomy system (into the 'term_node' table)." is set

Sorry for posting again with similar errors, but I need to get this working.
I tried a fresh setup with only the most necessary modules.
I hope I formulate this specific enough.

Setup:

PHP 5.3

Drupal Core 6.20
Modules
-Content 6.x-2.9
-ImageField 6.x-3.10
-FileField 6.x-3.10
-Administration menu 6.x-1.6
-content taxonomy 6.x-1.x-dev
-Exif 6.x-1.x-dev

I made two content types:
image and page
both with
-imagefield (default settings.)
-field_iptc_keywords Content Taxonomy Fields

When using the name "image" as content type, no filefields with exif were visible.
When using another name, with the same content fields, iptc_keywords show up.
However there is something wrong with the characters, it is showing utf8
ä in stead of ä
é for é

on the admin/settings/exif/general page I get following error:
warning: utf8_encode() expects parameter 1 to be string, array given in /.../sites/all/modules/exif/exif.admin.inc on line 23.
On the same page the example is showing the same problem with characters

keywords are added to the vocabulary
but there's no node-term relationship only

on the edit page of an existing node:
When setting the exif visibility settings to visible (admin/settings/exif/visibility "Show CCK Fields on Node-Creation form"
"Show CCK Fields on Node-Update form" )
I get the error: iptc_keywords cannot be longer than 255 characters but is currently 332 characters long.

When I set it to invisible I get following message.
warning: htmlspecialchars() expects parameter 1 to be string, array given in /.../includes/bootstrap.inc on line 857.

But strangely enough, I get no error message when I set "the Maximum length of auto-complete" to 1000

thanks for your time.

Is there somebody that can help on this or offer paid service?

one Problem was that utf8 coded info such were are coded again , weather they were already coded or not.

I have the thing working now, kind of...
when an image node is saved, only after re-editing, the save button is hit, the keywords are sent to the taxonomy module.
Any Idea how this can be cured?
