+This bug is a lockup of evas during rendering in my efl app.
+App freeze and takes 100% CPU. Below are backtraces when gdb was running and
+I interrupt it with Ctrl-C.
+
+At the time of crash, around 300objects total :
+elementary interface + ~100 edje + ~100 evas_object_line
+
+This crash is not predictible from what I see, sometimes it goes fine for a long
+time.
