+
+        We're getting reports of crashes in this function, caused by null or empty data being
+        passed to vImage. Guard against this, in a way that will ASSERT in debug builds if
+        anyone comes across it.
+
+        Test: css3/filters/blur-various-radii.html
+
+        * platform/graphics/filters/FEGaussianBlur.cpp:
+        (WebCore::accelerateBoxBlur): Return early if things don't look good.
