DB -> Entity: Reverse engeniering with two relations between two tables

i use the cli from the symfony 2.1 project to reverse from DB to Entity:

php app/console doctrine:mapping:convert xml ./src/Acme/StoreBundle/Resources/config/doctrine/metadata/orm --from-database --force

and i get tis error:

[Doctrine\ORM\Mapping\MappingException]
Property "radUser" in "RadAttribute" was already declared, but it must be declared only once

so i have a table "radUser" with two m:n relations to the same table "radAttributes":

Table radUser:
check => radAttributes
reply => radAttributes

so doctrine reverse mapping try to generate the radAttribute entity with two mapping to radUser with the same field name "radUser", what can i do to prevent this issue ?
