I'm not exactly sure how to reproduce this bug, but I did encounter the
same issue. It looks like the bug was recently introduced in this
commit:
https://git.launchpad.net/ubuntu/+source/apport/commit/?h=applied/ubuntu
/xenial-security&id=ecd7418b02911c6649b69a592cca74cfbac8813d

```
The problem is that os.O_PATH does not exist in python2, and only exists
in python3. However, python-apport is a python2 package.
```
bcurtiss@bcurtiss-laptop:~$ python3 -c 'import os; print(os.O_PATH)'

bcurtiss@bcurtiss-laptop:~$ python -c 'import os; print(os.O_PATH)'
Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute 'O_PATH'
