Comment (by nferrari):
Ok I updated the models to have a name CharField each, and inserted a few
objects (see dump.json).
The 1.5 shell returned:
{{{
In [1]: from foobar.models import *
In [2]: C.objects.exclude(a__flag=None).count()
Out[2]: 5
In [3]: C.objects.exclude(b__a__flag=None).count()
Out[3]: 4
}}}
While the new environment shell gives:
{{{
>>> from foobar.models import *
>>> C.objects.exclude(a__flag=None).count()
0
>>> C.objects.exclude(b__a__flag=None).count()
0
}}}
Old results are expected, let me know if you need more information.
