Right, I forgot this step in my test script, but it was done in the real
situation where I first noticed this behaviour.

Anyway, it doesn't change anything to this problem. Below is the new version of
the script I'm using to test this, and its output. As you can see, I'm doing a
svn up in the two working copies just before looking at the files, but still get
different values for the expanded $Rev$.


===== reproducer script =====

LC_ALL=C; export LC_ALL
set -x

svnadmin create repo
svn co file://$PWD/repo active
svn co file://$PWD/repo passive
cd active
svn mkdir dir
echo '$Rev$' > dir/file
svn add dir/file
svn propset svn:keywords Rev dir/file
svn ci -mdummy
svn cp dir newdir
svn ci -mdummy
cd ..
(cd passive && svn up)
(cd active && svn up)
head -v */newdir/file

===== script output =====
