Detailed description

Used to be able to load and use this model.

Since 3.4.0 release, fails with:

OpenCV Error: Unspecified error (FAILED: ReadProtoFromBinaryFile(param_file, param). Failed to parse NetParameter file: resnet_50_1by2_nsfw_new.caffemodel) in cv::dnn::ReadNetParamsFromBinaryFileOrDie, file C:\dev\lib\opencv-3.4.0\modules\dnn\src\caffe\caffe_io.cpp, line 1159

Steps to reproduce

Use DNN module to load the above linked module. It'll fail to load. Worked fine before 3.4.0. Just to be sure, rebuilt 3.3.1 from source just now and it does function in 3.3.1 but not 3.4.0 from release source.
