set_kws_threshold.py: Multiple words in keyphrase IndexError

Hi,

I have a problem with your set_kws_threshold.py script. If I use it with the following dictionary and keyword file I get an IndexError.

keyword file:

oh mighty computer /1e-49/
hello world /1e-49/
other phrase /1e-49/
go to one /1e-49/
go to two /1e-49/
go to three /1e-49/
go to four /1e-49/
go to five /1e-49/
start recording /1e-49/
stop recording /1e-49/
cancel recording /1e-49/
open camera /1e-49/
close camera /1e-49/
new action /1e-49/
new location /1e-49/
remember this /1e-49/
next screen /1e-49/
previous screen /1e-49/

Sorry to bother you with such a little problem, but I don't know python and that is why the error causing line exceeds my knowledge. But the line causes a problem, so you should probably know anyway.

BTW: The demo you've provided worked for me, so there should be no problem with my setup.

Thx for the work at cmusphinx :+1: Have a nice day :wave:
