[Python] How to debug an infinite loop in my Python anagram generator

The aim of the program is to generate an anagram given 6 randomly generated alphabets. The syntax seems to be correct but there's some sort of logical error which I am not able to figure out. If I execute the program then it will just go on running and won't stop.

I don't think it's because of any infinite loop, rather it's due to its inability to find anagram using the 6 generated letters. Have I made a mistake? I have highlighted the portion where I think there is error.

The file words.txt can be downloaded from http://thinkpython.com/code/words.txt.

import random

def game():

while True:
ch=[]
res=[]
print 'The 6 randomly generated alphabets are :'
for i in range(6):
ch.append(chr(random.randrange(97,123)))
print ch,'\n'
delimiter=''
z=delimiter.join(ch) #converted list to a string
word_list2=dict() #word_list2 is a dictionary containing randomly generated letters as keys
for c in z:
if c not in word_list2:
word_list2[c]=1
else:
word_list2[c]=word_list2[c]+1

fin=open('words.txt')
for c in range(130000):
words=fin.readline()
word=words.strip()
flag=1
if len(word)==6:

word_list1=dict() #word_list1 is a dict containing char present in word as keys

for c in word:
if c not in word_list1:
word_list1[c]=1
else:
word_list1[c]=word_list1[c]+1

***for c in word_list2:
if c not in word_list1:
flag=1
break
else:
if word_list1[c]==word_list2[c]: #comparing if characters in both dict have same no. i.e 'a' should occur 2 times in both etc
flag==0
else:
flag=1
break***



if flag==0:
res.append(word)

if not res:
print 'the list is empty'
print 'Selecting a new set of randomly generated characters\n'

else :
print res
break

game()
