Comment 4 for bug 1260017

For what its worth, providing backwards compatibility for this *user surfaced* configuration consists of doing this:

$ diff -u keyring/backend.py.smdist keyring/backend.py
--- /usr/share/pyshared/keyring/backend.py.smdist 2013-12-12 10:25:28.576780465 -0500

 from keyring import errors
 from keyring.util import properties
 from keyring.py27compat import add_metaclass, filter
+from keyring.backends.file import PlaintextKeyring as UncryptedFileKeyring

 import keyring.util

To be clear, your suggestion that you fixed all the packages in Ubuntu that might have used this is not sufficient to actually provide backwards compatibility.

I found this by using a package in ubuntu that previously worked and was broken after an upgrade.
