Are you using a file manager?  Normally one sees this behavior with a file
manager that tries to ascend the directory tree and stat directories, and
when it does this in /afs, it gets unhappy.

If you're seeing this using cp and ls and the like from the command line,
I've never seen anything like this before.

Are you using -dynroot -fakestat?  That often helps considerably and is
the recommended configuration at this point.  If your configuration
changed during the upgrade, that could explain why you saw this change.

It's very unlikely that any of the changes in the Debian package would
have affected this.  I did just upload 1.4.2-fc2 packages, but I haven't
heard of changes in this area in particular.
