Error: sed: -e expression #1, char 86: unknown option to `s'

Hi,

I am getting this with 1.6.5 (I was able to use the same values.yaml up to 1.6.4 and xwiki 17.4.8 included):

Path: /usr/local/tomcat
Configuring XWiki...
Setting environment variables
  Deploying XWiki in the 'ROOT' context
Replacing environment variables in files
  Setting permanent directory...
  Configure libreoffice...
sed: -e expression #1, char 86: unknown option to `s'

And the installation stops.

BTW, I'm still applying this hack (I have not refreshed the values for a while though) and it looks like it's still required but the status is unclear for recent versions.
