Please make sure that you've read the documentation before submitting a bug report. If you're sure you've found a bug - e.g. if one of my programs crashes with an obscur error message, or if the resulting file is missing part of the original data, then by all means submit a bug report. I use Bugzilla as my bug database. You can submit your bug reports there. Please be as verbose as possible - e.g. include the command line, if you use Windows or Linux etc.pp. If at all possible please include sample files as well so that I can reproduce the issue. If they are larger than 1M then please upload them somewhere and post a link in the bug report.
