The message view is empty when trying to view messages on www.hotmail.com. Patch r181993 looks like an excellent patch, and passes all stress tests on Win32, but bisecting suggests it was introduced by this patch.
Can you please check if this issue still manifests after http://trac.webkit.org/changeset/182745? If not, then this is likely a dup of https://bugs.webkit.org/show_bug.cgi?id=143407.
Yes, it is still an issue after r182745.
This is working now, sorry for the noise :)
