Description

I am using the Model.objects.raw() function to write my own custom query. This works perfect on my local machine (Python 2.6.1) but it does not work on the server (Python 2.5.2).

Creating the raw query set works fine, but as soon as I want to iterate over it, I get this error:

__init__() keywords must be strings

Traceback:
