I am experiencing the same issue. It occurs when building a dictionary for unk.def. It is not clear that this issue is caused by nori or by mecab korean dictionary. However, I could rebuild kuromoji analyzer successfully, so I suspect that it is related to mecab korean dictionary. This is because nori is derived from kuromoji, and the two analyzers are similar to each other.
