A regression test is required BEFORE logging a bug report.
It's not, but it's highly encouraged.
To David's point, most of us are volunteers, and users also have limited time. But since most volunteers likely don't care about your particular program, your issue is much more likely to get attention if the user runs the regression test. Depending on a volunteer group not only for free software, but to also spend particularly dedicated time to a program they don't know or care about is unlikely to yield the expected results.
Regardless, be nice people. We all want wine to be better, no need to attach each other.
