shutdown

----------------------------+--------------------
With the following model and a management command script that creates
several instances of this model - some with `point = None` - I get a
traceback on shutdown of the management command script. Note that the
instances are created/saved to the database perfectly fine. I also am
'''unable to reproduce''' without gevent.
{{{
from django.contrib.gis.db import models
class Provider(models.Model):
point = models.PointField(blank=True, null=True)
}}}
Management script:
{{{
from django.contrib.gis.geos import Point
from django.core.management import BaseCommand
from businesses.models import Provider
class Command(BaseCommand):
def handle(self, *args, **options):
for i in range(100):
Provider.objects.create(
point=Point(-123.329773, 48.407326)
)
Provider.objects.create(
point=None
)
}}}
Finally, the traceback:
{{{
(geos_exception)vagrant@vagrant-ubuntu-trusty-64:/vagrant/geos_exception$
./manage.py testcomm --settings=geos_exception.settings
Exception ignored in: <bound method WKBWriter.__del__ of
<django.contrib.gis.geos.prototypes.io.WKBWriter object at
0x7f7b62d85198>>
Traceback (most recent call last):

packages/gevent/local.py", line 246, in __getattribute__
TypeError: 'NoneType' object is not callable
}}}
I am attached a tar.gz file containing the test project. Remember, this
issue is intermittent - I can run the management command a time or two
without traceback before seeing the problem.
