permission error in import

[sggreener]

I am seeing lines like this in the log from an import.

[1] src/databasemodel.cpp (3116)
  void DatabaseModel::addPermission(Permission *)
    [AsgDuplicatedPermission] There is already a permission on object `ACHRIS' (Database) which has one or more equal roles from those present on permission to be assigned to the object!

I don't know what this means. Any indications welcomed!

regards
Simon
