Thanks for the explanation. I get it now. I think that this is the bug there:
We should be extracting at least the obsolete file (and perhaps locate.database)
from the etc set instead of doing special things in the postinstall script because
we are not even guaranteed to have the sources around.

That is minor and I will take care of it. I just don't think it is the right
way to fix it because it does not work all the time and the decision
whether to use the source instead of the installed files is done in
another place. How hard would it be to fix the upgrade process instead to
extract those two files?
