bulk_stem fails

[CodingLappen]

Hello I have been identifying an error without whilst using bulk_stem with unidentified words.
In hunspell,pyx line 529
ret_dict[unknown_words[i]].append(c_string_to_unicode_no_except(output_array[i][j], self._dic_encoding))
the value ret_dict[unknown_words[i] is tuple and therefore probably wasn't converted.

Thank you, it would be nice if you would fix it.
