pre-revprop-change Script Runs Twice and Fails for Some Revisions, Runs Once and Succeeds for Others

Hello all,

On the same repository, setting the 'svn:author' revision property
succeeds
for some revisions, but fails for others.
The error message is:
--------
svn: DAV request failed; it's possible that the repository's
pre-revprop-change hook either failed or is non-existent
svn: At least one property change failed; repository is unchanged
--------

I added some 'echo >> tmpfile' statements to my pre-revprop-change
script, and I saw that in cases where the
change fails, the script actually runs TWICE, whereas if it succeeds, it
only runs ONCE.

I am using Subversion 1.1.4 (r13838) on Debian, with Apache as the
server.

Here is an 'ls -l' of the hooks directory:
------------------------------
servername:/svn/abc/hooks# ls -l
total 28

------------------------------

This is the what the pre-revprop-change script looks like:
--------------------------------------
REPOS="$1"
REV="$2"
USER="$3"
PROPNAME="$4"

#if [ "$PROPNAME" = "svn:log" ]; then exit 0; fi
#exit 1

if [ "$PROPNAME" = "svn:author" ]; then
  echo "=========" >> /tmp/auth.txt
  echo "svn:author" >> /tmp/auth.txt
  echo $REPOS >> /tmp/auth.txt
  echo $REV >> /tmp/auth.txt
  echo $USER >> /tmp/auth.txt
  echo $PROPNAME >> /tmp/auth.txt
  echo "++++++++" >> /tmp/auth.txt
  exit 0;
fi

exit 0
--------------------------------------

Finally, just for completeness, here is a sample of this behavior:
--------------------------------------
alont@host:/mgmt$ svn propset --revprop -r886 svn:author "AlonT"
property 'svn:author' set on repository revision 886
alont@host:/mgmt$ svn propset --revprop -r849 svn:author "AlonT"
svn: DAV request failed; it's possible that the repository's
pre-revprop-change hook either failed or is non-existent
svn: At least one property change failed; repository is unchanged
--------------------------------------

I have focused on 'svn:author', but all the above details seem to apply
for 'svn:log', as well (without the check for 'svn:author' in the
script, obviously).

Many thanks,
Alon
