I'd have certain doubts of someone who does produce lots of open-source code, insofar as that could be construed as they don't think highly enough of their own code to sell it. Also, people who do volunteer work are obviously unqualified. I find such flaws tend not to occur in "closed" software, where someone is paid to polish the corners that nobody wants to. "A" bug in gcc proves that open source stinks? Have you used IE6?
