What is the license of oxygen icons? [POSSIBLE LICENSE VIOLATION]

oxygen-icons.org seems to have disappeared, making it harder to know a 
definitive answer.

I'm trying to determine what is the actual licensing of the oxygen 
icons, in connection to possible violations thereof. Specifically, 
http://openiconlibrary.sourceforge.net/ claims they are dual-licensed as 
CC-BY-SA 3.0, but I am unable to confirm this claim, and Wikipedia, 
Fedora and http://techbase.kde.org/Projects/Oxygen/Licensing all claim 
that they are licensed *only* under LGPL. (Additionally, COPYING in the 
tarballs only gives LGPL.)

Is there any truth to the CC-BY-SA claim? If not, is there someone to 
whom I should be reporting this violation?

(It's worse than just openiconlibrary; who knows how many users are 
using the icons in violation of LGPL...)
