Ok, with this additional option, if I start with chromium and try to
install kde-meta it still suggests unsetting icu, which is going to
lead to future errors (or breaking chromium).

If I start with kde-meta and try to install chromium the conflict is
detected, but it does not suggest setting icu on qt-webkit:
  !!! Multiple package instances within a single package slot have been pulled
  !!! into the dependency graph, resulting in a slot conflict:

  dev-libs/libxml2:2

    (dev-libs/libxml2-2.8.0_rc1::gentoo, installed) pulled in by
      dev-libs/libxml2:2[!icu?] required by (x11-libs/qt-webkit-4.8.2::gentoo,
  installed)

    (dev-libs/libxml2-2.8.0_rc1::gentoo, ebuild scheduled for merge)
pulled in by
      dev-libs/libxml2[icu] required by
(www-client/chromium-20.0.1132.43::gentoo,
  ebuild scheduled for merge)

So, seems like there is still room for improvement...
