Rails 3.0.5 "datum/data" inflection rules are used for all words ending with "ta"

I understand that Rails 3.0.5 changed the pluralization/singularization rules to support "datum" <-> "data", "stratum" <-> "strata", etc.

However, this seems to causes all words ending with "ta" to be pluralized incorrectly.

For example, "delta".pluralize => "delta" and "quota".pluralize => "quota".

The workaround I am using is to fix individual words by adding a rule to config/initializers/inflections.rb like

inflect.plural /(del|quo)ta$/, '\1tas'
