More detail message on schedule error

Hi,

Regarding the schedule error, it is log the message.
I think, it will be good to add the model id in the message.
So that, system administrator directly know which record might cause the problem.

We already have an issue on the tracker to improve such messages:

Unfortunatly, nobody has provided a solution for it. Any help on that will be much apreciated.
