Bug#457929: python-debian: _multivalued.dump() not working on multivalued fields

[Filippo Giunchedi]

Package: python-debian
Version: 0.1.7
Severity: normal

Hi,
consider the following code:

>>> from debian_bundle import deb822
>>> f = file("zsh_4.3.4-dev-6-3_all.changes")
>>> c = deb822.Changes(f)
>>> print c
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/var/lib/python-support/python2.4/debian_bundle/deb822.py", line 247, in __str__
    return self.dump()
  File "/var/lib/python-support/python2.4/debian_bundle/deb822.py", line 435, in dump
    fd.write(key + ": " + self[key] + "\n")
TypeError: cannot concatenate 'str' and 'list' objects

after a bit of investigation it seems that the key lookup in dump()
is not case insensitive though _multivalued_fields keys are required to
be lowercase. Note that using Files instead of files as key in
deb822.py:470 works as expected.

thanks,
filippo
