LanguageIDFilter filter error

When using LanguageIDFilter filter I got an error below :

Traceback (most recent call last):
  File "./bin/opusfilter", line 27, in <module>

I could produce this for the case that the output data is empty, i.e., the filter removes everything. There's now a fix in the master branch. Could you confirm that it helps?
