erroneous 'undefined name' in exception handling + lambda

$ cat pyflakes-test.py
try:
    raise Exception("test")
except Exception as e:
    print(e)
    x = lambda: e
    print(x)
    print(x())

$ pyflakes --version
1.5.0

$ pyflakes pyflakes-test.py
pyflakes-test.py:5: undefined name 'e'

running this with older pyflakes seems to work OK:

$ pyflakes --version
0.8.1

$ pyflakes pyflakes-test.py && echo $?
0
