Fighting massive data loss bugs

Slightly (but only slightly) off-topic, I feel that it is a shame that people suggesting ways non-programmers can contribute to free software don't emphasise this sort of collaboration enough. It can be done with minimal (though not non-existent) technical skills and no knowledge of programming, and I'm pretty sure that seeing bugs fixed as a result of this sort of work is the sort of rewarding experience that makes people want to use free software.
