Failing using "logerrit testfeature" - ERROR: missing Change-Id in commit message footer

I'm trying to use "logerrit testfeature" as Thorsten suggested here
<http://lists.freedesktop.org/archives/libreoffice/2015-July/069519.html>.
Unfortunately I get the error below at some point.
I tried to install the hook suggested but I get the same error (what I did
was: I modified the logerrit script to launch the suggested "scp" command
right before making the commit).

Any suggestions?
