Quoting the author of caption:
---------------
This is an error which will be fixed in the very next version of the
caption package which is planned for release end of this month.

Until then the following workaround can be used:

Please insert the following line right after \usepackage[...]{caption}:

\DeclareCaptionType{copyrightbox}

This should fix the problem and should not do any harm.
