When did they change the behavior of system.debug to not show  null values? It makes troubleshooting irritating during testing/debugging. Is there an alternative method to quickly pull back all of it?

In regards to insert task -  must've deleted it when I pasted into the window above. Regardless though - there may be something else going and it's not properly spitting out an error like I would expect. Doing some prodding around a custom Apex_Errors__c object I have and it's returning someting like this:

16:48:46:770 USER_DEBUG [76]|DEBUG|apex errors: (Apex_Error__c:{Id=a2i8A00000003GMQAY, Apex_Class__c=TaskUpdateActivityInfoBatch, Error_Record__c=00T8A000002zf4AUAQ, Error_Details__c=Attempt to de-reference a null object}, ......

But it's there - here's the full beast atm if you want to verify my insert statement is in there.
