I posted this on CAY user list but as no one could help and this seems a real

But it just doesn't happen always, it seems to be related to context startup
becouse when it happens it happens every time, but when it starts and you get
no errors it will not raise the exception ever.
So I think this should be a problem with model loading or something like that,
I will try to attach the model causing the issues but in anyways when the error
occurs is when we are creating a SessionLogApi object that inherits (shared
table inheritance) from an abstract class SessionLog.
The same commit has another new object of class Session that is related to
SessionLogApi so Session object stores SessionLogApi id.
Please ask me for any extra information you need to identify the error, I will
hapily provide it.
