In case anyone is googleing its way here: I created a bunch of foul fields by doing a join with arcpy.AddJoin and then use arcpy.FeatureClassToFeatureClass to make the join permanent. That seemed to be the wrong way. I only could fix my foul fields by joining via arcpy.JoinField instead (better way, anyway...).
@steveoh: Thanks to pointing out that there is an issue with foul fields. I've gotten almost crazy over this...
