Interesting. Do you have some unicode characters in any fields? There's a snippet on the bulk loader page about how to handle these characters in your Importer:
http://code.google.com/appengine/docs/python/tools/uploadingdata.html import datetime from google.appengine.ext import db from google.appengine.tools import bulkloader import models class AlbumLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'Album', [('title', lambda x: x.decode('utf-8')), ('artist', lambda x: x.decode('utf-8')), ('publication_date', lambda x: datetime.datetime.strptime(x, '%m/%d/%Y').date()), ('length_in_minutes', int) ]) loaders = [AlbumLoader] Your error may be caused by UTF-8/ASCII incompatibilities, and this is where I would start looking.
