Since this build http://travis-ci.org/#!/symfony/symfony/builds/2378056 tests involving intl/ICU are broken on travis. The cause is the upgrade from Ubuntu 11.10 to 12.04 which saw an update of ICU from 4.4 to 4.8. The Locale component tests are incompatible with ICU 4.8 outputs, as they expect ICU 4.4 outputs.
