I'm afraid that what you need to do is get as small as possible an 
example that reproduces the problem by hacking out lots of your code 
until the problem stops occuring. Doing this usually helps me fix the 
problem, but if not, you can at least post the answer here ;-)

- Do any of your attribute names start with _v_ ?

- You may be running into problems with Acquisition and differing 
acquisition contexts...
