I'm aware of this Ubuntu patch, but I couldn't get a clear explanation of
what the issue it addressed was when I asked about it a few months ago.

I had suspected we might have a similar issues, but hadn't had a chance to
test upgrades yet.  This report suggests there is an issue, and we could just
add a conflicts even if we can't reproduce it, but I'm not sure what versions
we should be conflicting with...
