Looking for uses of exceptions, I ended with this grep:

grep -Pr "new.*exception[^\"']*get_string" *

There are a lot of bad uses of exceptions with get_string() calls within them. We need to take rid of that ASAP, both in "normal" exceptions (first param is the errorcode no point about one get_string() call there) and also webservice_access_exception (first param is debuginfo and it cannot be translated). I'd recommend to create one issue about his point (in case it does not exist yet).
