As reported in https://code.google.com/p/chromium/issues/detail?id=473558 there is a patch that has fixed the issue.
https://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/chromium&id=5c6dde4a40faa3ffcb58a9434c18cc0ac64a75fc Perhaps this could help restore the "search google for image" functionality? Cheers
