svn commit bug over NFS

From: Nelson Elhage <nelhage_at_MIT.EDU>

I'm experiencing a repeatable bug with svn 1.4.2 checking into a
NFS-mounted repository via a file:// path.

Any attempts to commit to the repository yield the following error:

Transmitting file data .svn: Commit failed (details follow):
svn: Cannot write to the prototype revision file of transaction '14-1' because a previous representation is currently being written by another process

The repository is NFS-mounted:

$ mount | grep /data
lunatique.local:/data on /data type nfs (rw,addr=

$ grep /data /etc/fstab
lunatique.local:/data /data nfs defaults,noauto 0 0

svn is 1.4.2:

$ svn --version
svn, version 1.4.2 (r22196)

I've talked to David Glasser about the problem, and he mentioned he
believes it to be related to subversion r21738.
