The exact layout of voikko_grammar_error is visible to client code through 
deprecated API and thus it cannot be changed. But you can change 

 typedef struct {
	voikko_grammar_error legacyError;
	char * title;
	GrammarChecker * checker;
 } VoikkoGrammarError;

(Actually VoikkoGrammarError could just as well be turned into a class.)
You need the reference to the grammar checker that created the error so that 
in voikkoGetGrammarErrorShortDescription you can do something like

  error->checker->translateErrorTitle(error->title, language);

Sounds reasonable.

I think the path could be derived directly from 
dictionary.getGrammarBackend().getPath() which is something CgGrammarChecker 
already has access to?
