HTMLDOC Problem:

Htmldoc produced no pdf-output.
Commandline:
/usr/bin/htmldoc --bodyfont Arial --fontsize 8 --headfootsize 1 --logoimage fileadmin/designs/lewe/img/lewe/logo_text.jpg -t pdf13  --webpage -f /app/web/typo3temp/hd_yva7FJ - 2>/app/web/typo3temp/se_9SwTka

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.
