Hello, Since around when I switched from Firefox 2 to Firefox 3 (or perhaps it is a coincidence), Polipo often crashes, especially when I go to nytimes.com. Setting dnsUseGethostbyname to false or true didn't help, but it wasn't hard for me to get a backtrace under valgrind; see below. The page is http://www.nytimes.com/2008/07/01/business/01epstein.html . Any thoughts?
Thanks,
Ken
