Has anybody encountered something like this? Appreciate your ideas!

Just found the answer here: http://www.eclipse.org/forums/index.php?t=msg&th=162167&start=0&

One should select not all the packages, listed after adding the source URL, but only Visual Editor SDK. Then it installs fine.

But personally I find it unusable.
