Signature does not work (coredump / zero division)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Created a signature that will look for AirPush Services:
[ { "SAMPLE" : "myairpushapp" }, { "BASE" : "AndroidOS", "NAME" : "AirPush", 
        "SIGNATURE" : 
        [   
            { "TYPE" : "CLASSSIM", "CN" : "Lcom/airpush/android/PushAds;" },  
            { "TYPE" : "CLASSSIM", "CN" : "Lcom/airpush/android/UserDetailsReceiver;" },                                                                                                      
            { "TYPE" : "CLASSSIM", "CN" : "Lcom/airpush/android/MessageReceiver;" } , 
            { "TYPE" : "CLASSSIM", "CN" : "Lcom/airpush/android/DeliveryReceiver;" }
        ],  
        "BF" : "a || b || c || d"  
    }   
]

2. run androcsign:
./androcsign.py -i ../androsign/airpush.sign -o signatures/testdb
3. run androsign on the same sample to verify:
./androsign.py -i myairpushapp -b signatures/testdb -c signatures/dbconfig -v

What is the expected output? What do you see instead?
Got the following output:

[...]
ADD ELEMENT 71
ADD ELEMENT 1542
ADD ELEMENT 126
ADD ELEMENT 297
ADD ELEMENT 4
ADD ELEMENT 4
ADD ELEMENT 145
 CMClustering init rows
 [SIGN:0 CLUSTERS:0 CMP_CLUSTERS:0 ELEMENTS:984 CMP_ELEMENTS:0 ERROR float division by zero

What version of the product are you using? On what operating system?
latest hg.

The Sample is also attached (pw infected)

Please provide any additional information below.
