Cannot get SVN to log the SVN-ACTION

Hello all,

I have a problem I can't find why it is occuring. Maybe someone has seen it
already.

On a httpd 2.4.7 running with svn 1.7.18, I set up the logging to output the
SVN-ACTION.

Now, preparing an upgrade, I wanted to do the same under httpd 2.4.10 and svn
1.8.10 without success.

The config looks like this

<VirtualHost ....>
  ...

  LogFormat "%{X-Forwarded-For}i;%h %l %u %t \"%r %L %{SVN-ACTION}e\" %>s %b"
svnlog
  CustomLog /svn/conf/apache/access_log svnlog env=SVN-ACTION
</VirtualHost>

With this config, on the latter system (svn 1.8.10), nothing will be logged
into access_log until I remove or negate the env parameter from the CustomLog
line.

I tried to diff between svn 1.7.18 and 1.8.10 in the mod_dav_svn module but
haven't found anything useful.

I also tried to increase the logging level (trace8) of log_config module and
core module, but did not see anything useful.

Anyone seen this before ?

thanks,
