Camera Calibration Loading Images error

When I try to load images for calibration in the Camera Calibrator tool, I get the error : Too many input arguments. I tried it via GUI and command line as well. Can someone please tell what might be the problem here.

I am guessing that you loading images from files. What are the file types? The error may be caused by a specific file or some of the files. If possible, try to narrow it down to a specific file that causes the error and attach the file here.
