[lug] Suspicous: "host"/"DNS" Showing Odd Results (Fedora)

Does your /etc/resolv.conf have settings for forcing a sort on
dns query results? This would only help if firefox uses the system
dns resolver.

Even if the crash is in openssl it is possible firefox cannot handle
a single ip with multiple PTRs and varying query result order. If things
work when you open the login pages with a time delay between them then I
would wonder about race conditions in ff.
