See bug 1316330 comment 24.

Hitting 'MOZ_ASSERT(mNativeKeyCommandsValid)' in PuppetWidget::ExecuteNativeKeyBinding.

Actually, the same issue was found in Bug 993714, but it was fixed only for synthetic events. By doing the same for delayed events solves the issue. I'll provide a patch and see if it's okay.
Jessica, I know you are working on this, so assign to you. Thanks for taking this one.

Hi Olli, this is for fixing the crash. If the native key bindings list is no longer available when the delayed event is dispatched, we request it again.

patch, v1.

So this gives a new meaning to mIsSuppressedOrDelayed. Atm it is set only for events which are suppressed or delayed so that later a new similar event is dispatched. But this sets the flag on those events which will be dispatched afterwards. At least document this new meaning in BasicEvents.h

Right, I will document this in BasicEvents.h. Thanks.
