Update to Chromium version 16.0.891. This update contains the newer version, but also some updates in the spec-file related to the chromium setuid sandbox. bnc#718016 was filed to get the approval of the security team on the setuid bit on the chrome_sandbox. This was approved, but the spec-file needed some work to make it also happen on older releases. The method used now is the one confirmed by Ludwig (stated in the bugreport). At this moment the chromium package in 11.3:Contrib and 11.4:Contrib are links to the package in Factory, therefore the necessity to have it build for older versions.
