I have waited some time and some Ubuntu updates, but the bug is still there:

Yes: find and du get confused about seeing inode numbers reused in what
they think is a single filesystem.

A lot of tools aren't working correctly any more, even ls:

root@tsmsrvj:~# ls -R /nfs/localhost/fex | wc 
ls: /nfs/localhost/fex/spool: not listing already-listed directory

In consequence many cronjobs and montoring tools will fail :-(

You can eliminate the problems by exporting and mounting single
subvolumes only 

This is not possible at our site, we use rotating snapshots created by a
cronjob.
