Package: python3-debian
Version: 1.0.1
Severity: normal
X-Debbugs-Cc: [email protected]
When trying to copy a `Release` object or any `_multivalued` subclass
the code calls the constructor via `self.__class__(self)` and then the
`_multivalued.__init__()` treats fields in ``_multivalued_fields` as
strings, even though they have already been parsed in the source object.
This leads to the following exception:
Traceback (most recent call last):
File "//home/em/deb822-test.py", line 18, in <module>
r2 = r1.copy()
File "/usr/lib/python3.13/site-packages/debian/deb822.py", line 602, in
copy
copy = self.__class__(self)
File "/usr/lib/python3.13/site-packages/debian/deb822.py", line 1761, in
__init__
for line in filter(None, contents.splitlines()): # type: str
