Hmm, this shouldn't be happening (or iconv implemenations are guilty in these
SEGVs). The MbToWc does decide whether to reset iconv state judjing
on the return value of iconv() (there are two cases - sequence is invalid or
incomplete - if it's invalid, state is reset automatically and buffer is
emptied- see the code). So, the 'else' you added needs to be removed.
