NoneType is the symbol that the Python programming language uses to describe a field that has not been initialized or provided with any value at all. In this case, for some reason I do not yet understand, Python wants to run that field as part of the program.

I may be able to help you further but I need more information:

1. What do you mean when you say , "I tried to import configuration parameters from one file to another"? Were you importing into OpenERP?
2. What did you previously export in order to get the data you show above?
3. Where did it come from?
4. Exactly which page in OpenERP are you at when you try to import?
5. What does the server log file show at the time of the error?
