Actually, I have a similar problem when I use filter("user =", user"). It's a permanent problem (not just when I do an insert and count() just after). On the dev server it works perfectly, but once deployed, it always returns no result. You can try it by yourself if you want, my app is
here:http://le-carton.appspot.com/

The code behind is approximately:

### model.py:  class Nickname(db.Model):     nick = db.StringProperty(required = True)     user = db.UserProperty()

class Ad(db.Model):     title = db.StringProperty(required = True)     description = db.TextProperty(required = True)     price = db.FloatProperty(required = True)     currency = db.StringProperty(required = True, choices = set(CURRENCIES))     country = db.StringProperty(required = True, choices = set(COUNTRIES))     creation = db.DateTimeProperty(auto_now = False, auto_now_add = True)     lastModif = db.DateTimeProperty(auto_now = True, auto_now_add = True)     owner = db.UserProperty(required = True)     visible = db.BooleanProperty(required = True) # default = true, set to false the item is sold     photo = db.ReferenceProperty() # reference to photo     tags = db.ListProperty(db.Key, default = [])     keywords = db.ListProperty(unicode, default = []) # include tags and words from title and description

### core.py

class UserHandler(tools.BasicHandler):   def get(self):     self.init()

    # Extract the nick from the user from the URL     user_nick = cgi.escape(self.request.path.split("/")[-1])

    nick_entry = model.Nickname.all().filter("nick =", user_nick).get()

    if not nick_entry:       return self.notFound()

    # I always get the nick_entry as expected

    target_user = nick_entry.user

    ads_select = model.Ad.all().filter("owner = ", target_user)     ads_select = ads_select.filter("visible =", True)

    count = ads_select.count()

    ads_select = ads_select.order(self.define_order(self.request))     ads = ads_select.fetch((page+1)*model.ADS_PER_PAGE, page*model.ADS_PER_PAGE)

    self.template_values["ads"] = ads     tools.prepare_ads(self.template_values["ads"])

    # [...]

It may be a mistake in my code, but then, why does it work on the dev server and not once deployed ? Do you think it's worth to do a bug report ?
