call to OpenGL ES API with no current context

My Unity app is working well on Android 2.2 device(Samsung GalaxyS SHW-M110S).
But the same app shows the following error in log and stop working after pause and resume by pressing home key, on Android 2.3 device(the same Galaxy S).

“E/libEGL (00000): call to OpenGL ES API with no current context (logged once per thread)”

It seems frequent issue when using opengl, but I hope someone has a workaround for Unity Android app.

Should I do something in OnApplicationPause() or in any other function?

I also facing same problem on all android phone.
