Expected Behavior

Given the following AIML:

<?xml version="1.0" encoding="UTF-8"?>
<aiml version="2.0">

    <category>
        <pattern> <set>place</set> SUCKS </pattern>
        <template> That is unfortunate </template>
    </category>

    <category>
        <pattern> * </pattern>
        <template> <star/> </template>
    </category>

</aiml>

and place.txt as below, where entries with multiple words exist:

Rio de Janeiro
New York
Tokyo

By entering the query below:

Rio de Janeiro rocks

It should output

Rio de Janeiro rocks

Current Behavior

By entering the query below:

Rio de Janeiro rocks

The program outputs:

Janeiro rocks.

note that the 'Rio de' is deleted for some reason. (Also reproducible with 'New York')

When the input does not match the first pattern, the system works perfectly, for example:

I like Rio de Janeiro

Steps to Reproduce

Use the above .aiml and .txt
Run with the following python code:

from programy.clients.embed.basic import EmbeddedDataFileBot
import sys


files = {'aiml': ['./'],
		 'sets': ['./'],
		 }

my_bot = EmbeddedDataFileBot(files)

for line in sys.stdin:
	print(my_bot.ask_question(line))

Context (Environment)

Version of Program-y: 4.1
Version of Python: 3.6.1
Operating System ( inc Version ): Mac 10.11.6
