Created attachment 261997 [details] backtrace I get this assertion: ASSERTION FAILED: !isUnreachableNode(m_target.get()) ../../Source/WebCore/dom/EventContext.cpp(43) : WebCore::EventContext::EventContext(PassRefPtr<WebCore::Node>, PassRefPtr<WebCore::EventTarget>, PassRefPtr<WebCore::EventTarget>) When I click on any input element (such as the text entry on this Bugzilla page). It's a quite recent regression, so I'm suspicious of r190153 and r190214, which recently modified this code (CC: Ryosuke).

Is this still happening after http://trac.webkit.org/changeset/190288 ?

Correction: the crash doesn't require the element to be focused. It occurs on hover, not on focus. (In reply to comment #1) > Is this still happening after http://trac.webkit.org/changeset/190288 ? Yes, unfortunately.
