This is not a bug. Roughly, graphicx defines filename parser as '\def\filename@simple#1.#2' in its files. So #1 is a filename #2 is an extension. files you are trying to include have dots in its names so this led to this bug. I have just renamed them and tried again - no problems occured.
FYI, the problem was described here: https://tex.stackexchange.com/questions/10574/includegraphics-dots-in-filename
