--- Comment #15 from Ryosuke Niwa <rniwa at webkit.org> ---
Given the backtrace, it looks like someone using GenericEventQueue isn't keeping event target's wrapper alive.
GenericEventQueue is problematic because it doesn't keep event target's wrappers alive automatically.
Each event target which gets added to GenericEventQueue needs to keep its wrapper alive.
