<pre>Source/opensource/WebKitGTK/Source/WebKit2/UIProcess/API/gtk/WebKitWebViewBase.cpp (863)
uint32_t sequence = GPOINTER_TO_UINT(gdk_event_get_event_sequence(touchEvent));
If the touch event is GDK_TOUCH_BEGIN, gdk_event_get_event_sequence returns the value incrementally. (like as 1, 2, 3, 4...)
But if the touch event is GDK_TOUCH_END, gdk_event_get_event_sequence always returns the '1'.
STDERR: ASSERTION FAILED: m_touchEvents.contains(sequence)
At this time, sequence=1 already removed at first invoked webkitWebViewBaseTouchEvent().
So it makes the crash.
We have to investigate why gdk_event_get_event_sequence always return the '1' when touch event is GDK_TOUCH_END.</pre>
