At the risk of asking "is it plugged in", your trace suggests that AccessibilityObject::accessibilityPlatformIncludesObject() calls AccessibilityRenderObject::textUnderElement().

AccessibilityObject::accessibilityPlatformIncludesObject() **used to** call AccessibilityRenderObject::textUnderElement(). BUT it no longer does. Removing that call was what was done in http://trac.webkit.org/changeset/140166. In fact, the reason it was removed (aside from being resource intensive) is because it was crashing when an element was being destroyed -- which is also the case in the backtrace provided in the opening report.

Therefore, if you indeed can still reproduce this bug even with the changeset I asked you about earlier, you should be seeing a different backtrace. Having that new bactrace would be helpful. If you are seeing the very same backtrace, I have to ask are you sure you are using a webkitgtk build which includes that changeset.
