inspect.formatargvalues assumes (incorrectly) that every argument in args is a key in values. This isn't very hard to break -- see the attachment for a complete example. |

The bug seems to be in inspect indeed:
import inspect
def fun(x):
del x
return inspect.currentframe()
inspect.formatargvalues(*inspect.getargvalues(fun(10)))
Attached a proof-of-concept patch that replaces the missing value with <deleted>. If the approach is ok, the same fix might have to be applied to other functions and/or other types of arguments.
