Importing HS Content Taxonomy CCK Field broken when importing more than one at a time

I now narrowed my exporting content types/cck fields problem down. When I try to import more than on HS Content Taxonomy CCK Field at once, all I get is a blank page. I figured this might have something to do with this issue: http://drupal.org/node/972862 - But actually, I really don't have a clue.

Ex- and importing the fields one by one works just fine, but it takes expensive time =)
