pynlpir.segment(text, pos_names='all') fails for certain texts when pynlpir.segment(text) doesn't fail

[kensk8er]

pynlpir.segment(text, pos_names='all') fails for certain texts when pynlpir.segment(text) doesn't, which is not an expected behaviour I think.

For example,

When text = u'其中，新增了甲卡西酮、曲马多、安钠咖等12种新类型毒品的定罪量刑数量标准，并下调了在我国危害较为严重的毒品氯胺酮的定罪量刑数量标 准。'

pynlpir.segment(text, pos_names='all') causes the following Error:

No handlers could be found for logger "pynlpir.pos_map"

TypeError Traceback (most recent call last)

The issue was found in "Ubuntu 14.04 and OSX 10.11.04". I've installed `pynlpir` by `pip install pynlpir`.
