Mac OS X 5.03, corrupt file?

I can’t download Mac version of 5.03 cleanly, I always get: “Image data corrupted” when trying to expand the dmg-file:
http://donate.libreoffice.org/home/dl/mac-x86_64/5.0.3/en-US/LibreOffice_5.0.3_MacOS_x86-64.dmg

I’m using El Capitan.

Error code + message, please. See also Q60884 + Q60334.

thanks, alex, for me this (60334) worked.

See Q60334 for fix (thanks @metaworx for report).
