862	Which field caused method_save to bomb out?	garthk	Adrian Holovaty	If method_save fails whilst trying to call pre_save on a field, it can be tricky to figure out which field caused the problem without wading to exactly the right place in the stack frame or riddling meta\__init.py__ with debugging code. To save everyone the effort, I've got a patch that'll append a descriptive message to the exception's arguments so the errant field name is obvious and easy to find from the last line of the traceback. 	defect	closed	Metasystem		normal	wontfix			Unreviewed	0	0	0	0	0	0
