"Przynieśliśmy ci chleb."

Translation: We have brought you bread.

[Zimowski]

Is "We have brought bread to you" wrong indeed?

[mihxal]

No, it is only difference in gramatical structure. In this sentence indirect object is put before direct object and in your sentece indirect object is put after "to". But the meaning still remains the same.
