Problems with NFS mounted filestore

For reasons to do with "seeing the light" about how to use Bazaar as a
Subversion client (it took Jelmer a while to convince me, but he got
there in the end :-) I am taking a new branch of a Subversion repository
I already had a branch of.

However, the branch consistently fails to work when run on a machine
which mounts the filestore over NFS.  I have just undertaken the branch
on the fileserver itself and that is fine.  I don't know if this is a
bzr or bzr-svn thing, nor whether it is a known issue, i.e. should I
report a bug?
