New submission from jvoisin <[email protected]>:
The attached file raises an `IndexError: tuple index out of range` exception
when trying to open it with
`zipfile.Zipfile('crash-23b7d72644702df94bfcfaab4c25b01ff31c0b38')`, with the
following stacktrace:
```
$ cat test_zip.py
import zipfile
import sys
with zipfile.ZipFile(sys.argv[1]) as f:
pass
$ python3 ./test_zip.py ./crash-23b7d72644702df94bfcfaab4c25b01ff31c0b38
Traceback (most recent call last):
File "./test_zip.py", line 4, in <module>
with zipfile.ZipFile(sys.argv[1]) as f:
File "/usr/lib/python3.7/zipfile.py", line 1225, in __init__
self._RealGetContents()
File "/usr/lib/python3.7/zipfile.py", line 1348, in _RealGetContents
x._decodeExtra()
File "/usr/lib/python3.7/zipfile.py", line 480, in _decodeExtra
self.file_size = counts[idx]
IndexError: tuple index out of range
$
```
The zipfile documentation doesn't mention that IndexError is a possible
exception for this method.
