Bug#994911: error modifying deb822 object while iterating

[Jelmer Vernooij]

Package: python3-debian
Version: 0.1.41
Severity: normal

Modifying a deb822 file while iterating over it results in a RuntimeError:

...
  File "/home/jelmer/src/debian-janitor/python-debian/lib/debian/_deb822_repro/parsing.py", line 2208, in iter_keys
    yield from self._kvpair_elements
RuntimeError: dictionary keys changed during iteration

(This doesn't happen with the default deb822 implementation)
