cgi.parse_header doesn't work on headers that contain combinations of double quotes and semicolons (although it works with either type of character individually).
>>> cgi.parse_header('form-data; name="files"; filename="fo\\"o;bar"')
('form-data', {'name': 'files', 'filename': '"fo\\"o'})
This issue is present in python 2.7 and 3.2. One solution is to change _parseparam as follows (same as email.message._parseparam):
def _parseparam(s):
while s[:1] == ';':
s = s[1:]
end = s.find(';')
while end > 0 and (s.count('"', 0, end) - s.count('\\"', 0, end)) % 2:
end = s.find(';', end + 1)
if end < 0:
end = len(s)
f = s[:end]
yield f.strip()
s = s[end:]

The email module header parser handles this correctly (if you make it a real header). For whatever that's worth :) |

Attached a patch against 2.7. It adds Ben's example as a test case, and his one-line change to the _parseparam helper function to fix the issue. |
