Trying to creating a security group returns non-informative error

[Matthias Runge]

When trying to create a security group, the name may not contain white spaces or numbers. Validation inherits 'invalid' field error message from CharField which is 'Enter a valid value'. That doesn't help and does not explain, why the name is not being accepted.
