This doesn't always happen when running trial twisted on Windows. Presumably this has something to do with there being a zip file on the import search path. Can you please verify this? Ideally, describe the execution environment in sufficient detail that someone else can reproduce the behavior.

I am running into this on Twisted 13.0 / Python 2.7 also:

This is strange: the only ZIP file on sys.path does not even exist: 

>>> f = "/home/ec2-user/app/lib64/python27.zip"
>>> f in sys.path
True
>>> os.path.exists(f)
False
>>>

How did it get there? How can I remove it? Why does ZipFile break in this case? Mmh .. any hints?

Probably the python27.zip which is on sys.path but does not exist in the filesystem is the pseudo element described  http://stackoverflow.com/questions/6948779/missing-c-windows-system32-python27-zip-file/6949048#6949048.

Sym linking 

ln -s /usr/lib64/libpython2.7.so.1.0 /home/ec2-user/app/lib64/python27.zip

does not help though.
