App crashes when after resuming

My game crashed on Kindle Fire after I went to background and resumed the app (via the carousel). Logcat prints this error:

02-13 21:25:29.242: D/PhoneWindow(3247): couldn't save which view has focus because the focused view org.cocos2dx.lib.Cocos2dxGLSurfaceView405603d0 has no id.@

I will test on other devices and see if it does the same. Can this be fixed?
I’m using Cocos2d-x 2.0.4.

Thanks in advance.
