Well I installed the binary version and it converted my database to the flat file format. However when running html2lrf I'm getting a segmentation fault.
This is after running a conversion
/usr/bin/html2lrf: line 6: 15019 Segmentation fault ./html2lrf "$@"
And this is after running it with no options
