Crash on OpenGL ES 3.0 Device..

Hi there

it seems that there is slight problem in the lastest version of ngui, under circumstances of kikat os and opengl 2.0, crashes occur.
(when i use opengl 3.0, crash doesn't occur. It works perfectly. But most of phones doesn't support opengl 3.0. it's not compatible) Followings are the conditions of problem

Manifest : opengl 2.0 version of ngui : 3.5.3 OS : kitkat (4.4.2) Phones : LG G2, Samsung Galaxy Note3, Galaxy S4 lte-a

ps. call stack is....
