Please file bugs about unreleased version of Safari via <http://bugreport.apple.com>. Also, please note that nightly builds are only designed to work with the latest released version of Safari.
Hmm, but nightly was working until that build. Still seems important that something changed to introduce an issue to the next Safari from a nightly build update.
(In reply to comment #2) > Hmm, but nightly was working until that build. Still seems important that something changed to introduce an issue to the next Safari from a nightly build update. The WebKit project strives to remain backwards compatible with *released* software, not unreleased software. You're using an unreleased version of Safari.
