Bug 25947 – Assertion failure in FrameLoader::transitionToCommitted on launch in Safari with r43985

• Component: New Bugs
• Status: RESOLVED FIXED

[Jon]

When trying to use ToT from Safari, the application freezes at launch and must be force quit. I'm told it's hitting an assert at FrameLoader.cpp:2946. Here's the applicable stack trace: 

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x00000000bbadbeef
