New submission from Tomasz Miąsko <tomasz.mia...@gmail.com>:
Using ndb.ndbm get when key is missing and default value has to be returned
results in invocation of Py_INCREF on null pointer. Test case to reproduce the
issue:
```
import dbm.ndbm
with dbm.ndbm.open('db', 'n') as db:
print(db.get('missing-key'))
```
