I'm trying to convert a (huge) HTML page to MOBI with calibre 0.7.59. When I press the "Ok" button on the convert window calibre closes imediatly. I already tried turning on debug options but couldn't get any info: debug output files are always empty. I tried the file as one single page and as 20 separate pages. The same problem happens on all cases. What should I do to further debug this issue?
The HTML page to be converted is
