Problems found testing with Drupal 5.3

Hello my friends,
I've installed this module in my Drupal 5.3. I set an integer cck field to be editable in one of my content types, and I got the following errors:

• Submitting a comment in a content type WITHOUT any cck field marked as editable:

  # warning: array_merge() [function.array-merge]: Argument #2 is not an array in /mnt/san/usr/home/loquepasaentenerife.com/web/modules/comment_cck/comment_cck.module on line 85.
  

  # warning: Invalid argument supplied for foreach() in /mnt/san/usr/home/loquepasaentenerife.com/web/modules/cck/fieldgroup.module on line 395.
  

  This one for more than 40 times

• Submitting a comment in a content type WITH a cck integer field marked as editable and set to 0 for initial value:
  

  
      * warning: Illegal offset type in isset or empty in /mnt/san/usr/home/loquepasaentenerife.com/web/modules/taxonomy/taxonomy.module on line 1172.

      * warning: Illegal offset type in /mnt/san/usr/home/loquepasaentenerife.com/web/modules/taxonomy/taxonomy.module on line 1176.
  
  

  AND, and this is what drives me crazy, it seems to change the value o MORE cck fields than I set as editable, making my content going nuts!

If I disable this module, everything works fine.
Any idea?
Thank you in advance, and sorry for my poor English
