module l10n_pt_base in trunk-addons-community has wrong category

the module l10n_pt_base has the category wrong, in file __terp__.py is:
 "category" : "Localisation/Account charts",
but other account charts modules have:
 "category" : "Localisation/Account Charts",

case sensitive is important

this is why can be set in table ir_model_data the constraint:

ALTER TABLE ir_model_data
  ADD CONSTRAINT ir_model_data_module_name_uniq UNIQUE(name, module);

with error:
ERROR: could not create unique index "ir_model_data_module_name_uniq"
Stato SQL: 23505
Dettaglio: Key (name, module)=(module_category_localisation_account_charts, base) is duplicated.
