Again Exceptions in GEOS I/O object destructor at process exit

[Matthieu Rigal]

Very similarly to #13488 I saw these tracebacks in GeoDjango when I quit :

Exception TypeError: "'NoneType' object is not callable" in <bound method _WKBReader.__del__ of <django.contrib.gis.geos.prototypes.io._WKBReader object at 0x10704ea50>> ignored
Exception TypeError: "'NoneType' object is not callable" in <bound method WKBWriter.__del__ of <django.contrib.gis.geos.prototypes.io.WKBWriter object at 0x10705a290>> ignored

I experienced that on Python 2.7.4, Django 1.5.1 with Gdal 1.10, Geos 3.3.5, Postgres 9.2.4 and PostGIS 2.0.1 on MacOSX 10.8. And I do not have module-level globals.

The funny thing is that the warnings disappeared after some work, I tried to recreate the original conditions (prints, errors, etc..) but I do not manage to reproduce these errors I had 2 times in a row when quitting the runserver... In any case, seems very minor... Maybe some other may confirm the same behaviour.

I'm afraid it will be difficult to fix if we cannot come with a reproducible test case. If anyone can provide a failing test, please reopen the ticket.

I'm receiving the same error with Python 2.7.7, Django 1.6.5, Geos 3.3.8, Postgres 9.3.1.0 (18) - using ​http://postgresapp.com/ and Mac OSX 10.8.5. It occurs every time I run a test, shell or a management command which accesses a database object which contains a gis_models.PointField

For example:

Python 2.7.7 (default, Jun  2 2014, 18:53:46)

Where models.py is

class Location(BaseModel):

    name = models.CharField(max_length=255)

    point = gis_models.PointField(default="POINT(0.0 0.0)")

    @property
    def latitude(self):
        return self.point.y

    @latitude.setter
    def latitude(self, value):
        self.point.y = value

    @property
    def longitude(self):
        return self.point.x

    @longitude.setter
    def longitude(self, value):
        self.point.x = value

Could you maybe provide BaseModel also, or even better a complete sample project?
