When adding a user to a group that they are already a member of get "User is invalid"

When you try adding a user to a group they are member of, you get "User is invalid" instead of something that says, already a member, or something to that effect?

We try not to hardcode any error messages and just act like a proxy where possible, so in this particular case this error comes from Redmine API directly, we could somehow try to retranslate the message to a valid one, but I don't think that's the right way as they can change the error message on their side and our fix won't be working any more, so I believe the right way is that it should be fixed on their side and not ours.
