Remember!

  Whenever you report an error, include the traceback (together
  with the information your provided above!).


Apparently, you have been able to catalog a "mybrains" instance.
"mybrains" instances cannot be unpickled (deserialized)
as the class "mybrains" is locally defined inside a function.
Therefore, they must not be made persistent or used as or in attributes
of a persistent object.
