Error when disassembling a file

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Disassemble a .net file with ephash with the following code:

import sys
import pefile
import pydasm

file = sys.argv[1]

pe =  pefile.PE(file)

print "EP: " + str(pe.OPTIONAL_HEADER.AddressOfEntryPoint)

ep = pe.OPTIONAL_HEADER.AddressOfEntryPoint
ep_ava = ep+pe.OPTIONAL_HEADER.ImageBase
data = pe.get_memory_mapped_image()[ep:ep+100]
while offset < len(data):
  i = pydasm.get_instruction(data[offset:], pydasm.MODE_32)
  print i.length
  print pydasm.get_instruction_string(i, pydasm.FORMAT_INTEL, ep_ava+offset)
  offset += i.length

What is the expected output? What do you see instead?
I wanted to see the disassembly.

I get this error:
Traceback (most recent call last):
  File "statictest.py", line 17, in <module>
    while offset < len(data):
NameError: name 'offset' is not defined

* The file attach is the file on which i tested.
I could get it to disassemble only the first line.

Help would be appreciated.

From you code snippet and the error message it appears that "offset" is not 
defined.

My bad, it was a different python code.
This is the error:

Traceback (most recent call last):
  File "statictest.py", line 18, in <module>
    while offset < len(data):
OverflowError: long int too large to convert to int
