It looks like a bug in p5-Crypt-SSLeay, and it not properly calling some OpenSSL routines, which causes perl to segfault. In fetchyahoo 2.10.6, it is on line 1435 of 2117, which reads: $main_page = $ua->request($request); $ua is a LWP::UserAgent object, and what's happening is that the request is redirecting to an SSL page, so even if you have SSL turned off it will end up making an SSL request. I fixed it (very temporarily) by removing p5-Crypt-SSLeay (pkg_delete -f p5-Crypt-SSLeay). The UserAgent object sees that it can't do SSL without that package and follows the redirects but without SSL. So obviously there is the drawback that SSL won't work, and also I have other packages that rely on that perl module (notably gnucash) that won't work with it not installed. That bug was filed with Debian a year ago (Bug#334938, Oct 20, 2005 ).
