autonose dies when using custom exception class

[winstonewert]

My code in test_fail.py

class SomeError(Exception):
    pass

def foo():
    raise SomeError()

def test_foo():
    foo()

When I invoke autonose --debug:

It looks like something is trying to unpickle the exception object from inside test_fail.py. However, it cannot import it probably because its not on sys.path, but rather in the local directory.

Thanks for the report. autonose already avoids pickling the exception instance itself, but still pickles the type. That's unnecessary (we only need the name of the type), so it's fixed in f627933
