Bug#597120: python-debian: Changes: Should raise exception when serializing invalid data

[Jelmer Vernooij]

Package: python-debian
Version: 0.1.17~bzr184~launchpad1
Severity: normal


The Changes() object (but probably other deb822-style objects as well)
don't handle the situation very well when a field that contains empty
lines is followed by another field:

#!/usr/bin/python
from debian.deb822 import Changes
x = Changes()
x["Changes"] = """Foo

Bar
"""
x["Format"] = "1.8"
y = Changes(x.dump())
print y["Format"]

It would be nice if an exception was raised instead of an invalid changes file
being written.
