i just copied your new code from the howto and changed the username/password variables.
started the script with --verbose but it still hangs at 100% cpu. simultaneously doing "show processlist;" in mysql doesn't show the fuzzyocr user connecting.
manually connection with the username/pwd to mysql seems to be OK:
mysql -ufuzzyocr -p*password*
maybe a perl-DBI problem? how can i simply debug this.
