Spell checking always set to English - where's the setting?

Binary package hint: empathy

I cannot find a place where the language for spell checking can be selected nor can I find a place where spell checking could be disabled completely!
This is really, really annoying and not really understandable.

A setting for Empathy in general would really be needed, but for the long term this setting should be contact specific!
