Kubuntu 11.04. The Tbird 5 was from the Mozilla PPA, which no longer
makes it available for download and manual installation.

Yes, I am a regular tester and triager of Virtual Identity. The fix is
already released and Thunderbird is now working again. However, I do
need to know how to handle these situations for software that I am not
in contact with the devs.
Alan, what is your opinion of Yum? I see that it is in fact available
for Ubuntu. Yum can be configured to remember software versions and
configurations. When so configured, the user can simply rpm -Uhv
--rollback 'august 16' and be done with it. I cannot find a similar
feature for aptitude.

That wants to remove Enigmail and then reinstalling Enigmail will be
an engima. I'm a bit afraid of that route.

They don't have it available! At least, I cannot find it. Wait,
scratch that, googling Mozilla mirrors at least finds me a few mirros
that still have the tarball.

That was my plan. Now that Virtual Identity is fixed the issue is less
critical, but the secondary goal of knowing how to roll back is still
important to me. Mozilla plans on updating Tbird every three months. I
like to keep a reasonably-new Tbird as Thunderbird Conversations
pushes many patches to Mozilla and many features of Conversations
require a very recent Tbird. So I will inadvertently break it again.
In other words, I need to learn how to handle living near the bleeding
