Yes, I can reproduce it:

```
$ python3 --version
Python 3.9.9

$ python3.9 ziprepo.py ./crash-4da08e9ababa495ac51ecad588fd61081a66b5bb6e7a0e791f44907fa274ec62 
Traceback (most recent call last):
  File "/home/jvoisin/Downloads/ziprepo.py", line 4, in <module>

  File "/usr/lib/python3.9/zipfile.py", line 1257, in __init__
    self._RealGetContents()
  File "/usr/lib/python3.9/zipfile.py", line 1342, in _RealGetContents
    fp.seek(self.start_dir, 0)

The *binary* is a corrupted zip file to open with `zipfile.ZipFile()`, it can't be executed on its own.
