Backtrace for the Webkit Process crash

In WebKit Nightly 528+, if any text entered into a text input, or textarea, is corrected by OSX's autocorrect, the WebKit process crashes.

This can be reproduced every time for me. Enter some text into a text field that you expect to be corrected, and as soon as the correction occurs, the WebKit process will crash. For example, typing "youre" followed by the spacebar will replace the entered text with "you're", and at this moment, WebKit crashes, with the "An error occurred with this webpage so it was reloaded" banner.

I have attached a simple reduction, a backtrace for one of the crashes, and a gif animation demonstrating the bug.
