"ProgrammingError: syntax error" when loading (JSON) serialized data

[eduardo.padoan@…]

I'm using rev. 4993. My model is:
(testproj.testapp)

from django.db import models

class TestModel(models.Model):
    name = models.CharField(maxlength=10)

Then:

$ ./manage.py shell
Python 2.5.1c1 (release25-maint, Apr  6 2007, 22:02:36)
[GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from testproj.testapp. models import TestModel
>>> test_obj = TestModel(name="Foo")
>>> test_obj.save()
>>>

...And:

$ ./manage.py dumpdata testapp
[{"pk": "1", "model": "testapp.testmodel", "fields": {"name": "Foo"}}]

OK it is there. Lets get it back:

$ ./manage.py dumpdata testapp > test.json
$ ./manage.py loaddata test.json
Loading 'test' fixtures...

    return self.cursor.execute(sql, params)

On "screen -U" (unicode), the error message ends on the ". I have to type Enter to get my shell back.
Without screen:

At first glance this appears to be a duplicate of #3790; are you using a Django Subversion checkout later than revision 4937 (revision 4937 was *after* the 0.96 release)?

Replying to ubernostrum:

As I said, I'm using revison 4993.
#3790 is an IntegrityError, no a ProgrammingError. In another test I cleaned the database before trying to load the .json, and the same error happened.

Hm. I think I was looking at the wrong ticket; #3954 sounds more like what's happening to you (the sequence reset is sending something bad to the DB).

Yes, the patch to remove colors on sql on #3954 resolved the problem. Thanks and sorry for the duplication.
