fast/ruby/base-shorter-than-text.html has a text failure on Lion and MountainLion. It was also previously reported as failing on SnowLeopard (see http://webkit.org/b/56519) but this has already been suppressed in TestExpectations. Probable cause: http://trac.webkit.org/changeset/138838
Modified TestExpectations: http://trac.webkit.org/changeset/138884 Ojan, can you confirm whether or not this is related to your patch?
