Created attachment 74207 [details] crash dump from r71499 (after opening site of the URL) Might be somewhere else, but anyway the crash happened after opening that page... PS As it certainly is easier to mark something as 'duplicate', I won't ever again attach several crash dumps in one bug!

This crash is deep inside non-WebKit code, I've moved it to Radar for engineers working on that code to investigate.
