Permutated columns when using Paginator with ValuesQuerySet

[micval@…]

I have this model:

class Document(models.Model):
    filename    = models.CharField(max_length=1000)
    filesize    = models.IntegerField()
    keywords    = models.CharField(max_length=1000)
    content     = models.TextField()

When selecting documents I don't want the content field to be selected (for performance issues), so I use values like this:

docs = Document.objects.values('id','filename','filesize','keywords')

But when feeding this list directly to Paginator, the columns get permutated, e.g.: Paginator(docs,3,3,True).page(1).object_list gives:

[{'keywords': 161, 'id': 1, 'filesize': u'sample file'}, 
{'keywords': 162, 'id': 2, 'filesize': u'another sample file'}, 
{'keywords': 163, 'id': 3, 'filesize': u'sample file'}]

If I "evaluate" docs first, the columns get their correct values:

[{'keywords': u'sample file', 'id': 1, 'filesize': 161}, 
{'keywords': u'another sample file', 'id': 2, 'filesize': 162}, 
{'keywords': u'sample file', 'id': 3, 'filesize': 163}]

I use l = len(docs) workaround in my views, which does the trick, but this behaviour puzzles me a little bit.

Fixed description. Please use the preview button to check your description in the future. Wiki syntax isn't like bulletin board syntax or whatever it was you were using and the text was unfortunately fairly unreadable.

Have you written any __unicode__ for your model? If so, you can paste here. It works fine for me.
here is my output.

>>> docs
[<Document: foo1>, <Document: foo2>, <Document: foo3>]
>>> from django.core.paginator import Paginator
>>> paginator = Paginator(docs, 3, 3, True)
>>> paginator.num_pages
1
>>> paginator.page(1)
<Page 1 of 1>
>>> paginator.page(1).object_list
[<Document: foo1>, <Document: foo2>, <Document: foo3>]
>>> paginator.page(1).object_list[2]
<Document: foo3>
>>> x = paginator.page(1).object_list[2]
>>> x.filesize
163
>>> x = paginator.page(1).object_list[1]
>>> x.filesize
162
>>> x.filename
u'foo2'

Can't reproduce this. Your example code gives the right answer - and not the second answer you posted, it includes 'filename' as it should.

Looking at Paginator, this bugs seems extremely unlikely, so I'm thinking something else must be going on.
