I'm building it on Leopard and linking it with RC on Leopard and
standard ruby on Leopard. (Although the build from Tiger didn't work
either.) I have the stack trace attached below (from my own exception
handler). The class "Action" is a ruby subclass of NSManagedObject. I
don't know where the super:valueForUndefinedKey call is coming from,
I'm never calling that method myself.
If I add the following method to the Action class, I don't get this
particular crash but another one. Curiosly, the method is never called.
def valueForUndefinedKey(x)
raise "Error"
end
