Unfortunately this still causes lots of noise in the Subversion branch
for every commit; see for example
<URL:http://lists.alioth.debian.org/pipermail/reportbug-commits/2008-June/000001.html>
which is the result of a merge into the Bazaar checkout of a
Subversion branch.

How can we avoid this property-change noise in the Subversion
repository when I use Bazaar on it?
