KeyError: 'exception match'

[antingshen]

I run this in a new notebook:

try:
    raise ValueError
except Exception as e:
    pass

and I get this error:

---------------------------------------------------------------------------

During handling of the above exception, another exception occurred:

Thanks for catching the bug Anting! We'll look into it next week and let you know an ETA for the fix!

I could not replicate this issue.

However, when I run

raise ValueError

I get the following.

---------------------------------------------------------------------------

AttributeError: 'super' object has no attribute 'visit_Raise'

This is a pretty ugly error.
