Type mismatch errors #449

when i set filter for GPUImageView , I ran into this problem:

Type mismatch: inferred type is jp.co.cyberagent.android.gpuimage.filter.GPUImageFilter? but jp.co.cyberagent.android.gpuimage.GPUImageFilter! was expected

I can sure that i use GPUImageFilter from xxx.gpuimage.filter.GPUImageFilter ,but why this error appeared?
