An easy way to reproduce is to have an environment variable named
"PROXY":
$ PROXY=toto ./python -m test.regrtest -F test_urllib
[ 1] test_urllib
Warning -- os.environ was modified by test_urllib
test test_urllib failed -- Traceback (most recent call last):
File "/home/antoine/py3k/debug/Lib/test/test_urllib.py", line 121, in
setUp for k in os.environ.keys():
File "/home/antoine/py3k/debug/Lib/_abcoll.py", line 410, in __iter__
for key in self._mapping:
File "/home/antoine/py3k/debug/Lib/os.py", line 441, in __iter__
for key in self._data:
RuntimeError: dictionary changed size during iteration
There doesn't seem to be anything really mysterious, actually. The
exception message says it all :)
