Objects lose attributes?

[kronosapiens]

I'm running into a strange bug -- my classes and objects will periodically forget their attributes, with the attributes being replaces with the relevant query fields.

For example,

>>> object.name
>>> 'name'

Becomes

>>>object.name
>>>QueryField(name)

I can fix the problem by re-importing the class, but that seems like a pretty bad solution. I haven't been able to pin this to any specific behavior on my end -- it happens every time, after some irregular length of time.
