Well, the simple answer is that there's something wrong with your machine's hardware or low-level software environment -- SuperDuper! has no kernel level components, so it can't be the cause of a kernel panic... though, because it exercises your machine a lot, it can trigger other parts to fail.

If you'll send a System Profiler report to support, I'll take a look and see what I can figure out. To do so, run System Profiler, choose File | Save and save to the default (XML) format. Then, attach to some email (don't post here in the forums).

Thanks.
