HTMLDOC Problem:

Htmldoc produced no pdf-output.
Commandline:

/usr/bin/htmldoc -t pdf13 -v  --webpage -f /opt/data/www/ira-nantes.gouv.fr/typo3temp/hd_82g4wU - 2>/opt/data/www/ira-nantes.gouv.fr/typo3temp/se_Y00DVC

This is the (stderr) output of the htmldoc command without the htmldoc_append parameters:
If you see no errors here please check your htmldoc_append parameters too.
