HTMLDOC Problem:

Htmldoc produced no pdf-output.
Commandline:
/usr/bin/htmldoc --size A4 --top 2cm --bottom 2cm --left 2cm --right 2cm --logoimage fileadmin/templates/truck-news/images/truck-news.gif -t pdf13  --webpage -f /var/www/vhosts/truck-news.de/httpdocs/typo3temp/hd_igBlkE - 2>/var/www/vhosts/truck-news.de/httpdocs/typo3temp/se_3n7eaC

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.
